Product Description

See the newest PARIS Sirius™  2017 Air F3 iNav HERE


PARIS Sirius™ AIR v2 HERO GPS return to Home  - with Full metal Jacket  - for mini Quad Racers  - MultiWii software - has one outstanding feature over all others is the "pilot feel" you get in 100% pilot manual Acro mode - it's called "HERO mode" or Acro  -  you are in control - it Is more crisp and more locked in than any other software/gyros only manual pilot mode - period - and we mean better feel than NAZA or any other software in 100% pilot manual control modes.  So if your the kind of person who believes that a "pilot" can fly better than an iRobot auto-pilot then this AIR is the Quad board of your dreams.  For us as pilots, it's not about all the "self-flying-drone" where you don't need any skill or training. We believe that pilots are skilled people. If you don't have this skill yet, you can learn skills on a simulator here - PARIS AIR features 100% control for "pilots"

For noob Q & A questions - see bottom of this page (Rev v2 4.4.14)

Whats New in the v2 HERO AIR ?  Answer = GPS Return to home RTH port - New more expensive BARO, smoother 3050 IMU sensors have been installed - the same as used in the super smooth PARIS v5 - (uses a modified AIR code Sketch - so please use only the v2 HERO code files below)

  1. different gyro = Invensense 3050 - why this older gyro? - because it just "so smooth to fly" superior Gyro in real-world drone vibe world - a lot more expensive to install -  it's a rare hard to find smooth gyro - however it's more suited to aerial ops being way less gritty than the theoretically better 6500/6050 , it allows faster/higher LFP settings for any given multicopter = smoother PARIS v5 feel in an AIR sized - full metal jackets AP - perfect for high risk "mini's"
  2. New Accelerometer Bosch 280 - the latest from the big german Bosch 
  3. New BARO MS5611 -  more expensive baro - mounted inverted and kept in the dark for even batter accuracy and pitot-static air sensing    paris-air-hero-3644.jpg

Options GPS? or oLED?

Can either be flown With GPS RTH ; or with an oLED ; default is supplied on a Knife with a GPS RTH (return to home by GPS if signal lost or pilot commanded) and or coded oLED if no GPS is selected or purchased  - choose one of GPS option at top right.  So if not sure - or if its 2nd hand - If you want to fly a GPS - flash the GPS sketch code and connect the GPS and power the GPS by 5v ; or if you want to fly a oLED then reflash with oLED Sketch and disconnect the GPs and in its place connect the oLED.  Devices cannot run on each others code - so you have to choose one or the other - then make sure the code for that device is flashed using Arduino 1.0.6 - see below - You cannot just disconnect a GPs - it will give errors.  You can however disconnect an oLED if coded oLED as the oLED does not send any data back to PARIS AIRv2 so wont give any errors if disconnected.


  • PARIS AIR v2 flight controller in metal case (Gyros, Acc, Baro included- pre-coded and pre-programmed - ready for pre-flight checks in UI
  • AIR adhesive GEL mounting tape (pre-installed - peel-n-stick with arrow facing front)
  • 8 pins RC cable for any RC Rx - see photos above
  • LED GND trigger lead for Andromeda v2 triggering  (excludes Andromeda)


Features carried over from AIR v1

  1. Re-thinking the c competition's lazy all-wires-exiting-all-sides - we decided to design for FPV so - all ESC and Rx wiring to come from the rear - a first - that meant placing the pins forward of the molex and the RC Rx underneath - solved
  2. We wanted the smallest possible core with 3 axis gyro, 3 axis Acc and a shielded inverted BARO - done - but it took a 4 layer 32u4 board and some cunning EE work to solve it.  Made in Korea - solved
  3. USB was a must and we wanted system level drivers - micro USB that was fast - 32u4 CPU selected because it has fast USB 2 level drivers.  You can bang on all day long about Arm CPU's for NAV - we agree - but for a Pilot quad-racer FPV board its simply not relevant because the motor speeds cannot be changed faster than 20 times a second - motors and props have inertia - so the 8bit 16mhz is plenty fast enough at 400hz on motor ESc control.  We tried the ARM chip controllers and there is absolutely no difference for this core function in manual modes used by FPV plots (outside of NAV and this is not a cross country drone - its made for Quad racers and FPV fliers)
  4. We wanted hardware 11 bit ESC control - The 32u4 Arduino CPU only has 4*11 bit hardware outputs - so these were all channeled specifically to the most important places - the 4 motor controllers M1->M4 - Core business focused - not mixed like other 32u4 boards
  5. We wanted it to have optional RTH GPS connectivity - we don't need PH because we can hold the hover better than any lame GPS for grand-dads - but when out on the edge of FPV and RC range we still needed RTH - sorted   paris-air-sbus-3668.jpg
  6. Inertial mass dampening - so now we cut to the real innovation - a small board needs inertial mass to resist vibration - so we deliberately made a bullet proof metal case thats so strong so can mount it out on top, or even crash it at Vne and it wont break - yet its mass "resists" vibration being transferred to the Gyros or the Acc ? What? Thats right - We here at Multiwiicopter.com realise that you never subject sensors to airframe vibration and our Sirius IMU has always ridden on a bed of isolation foam since Dec 2010 - important design fundamental - is inertial mass -  we took that one more step and placed the entire CPU inside the metal IMU isolation box.  Another first for MultiWiicopter.com   Don't think plastic cases are better because they are lighter - they don't resist vibs because their inertial mass is too low.
  7. Gimbal controls - We like gimbals a lot - so even though this PARIS Sirius Air was only meant for Quads and Triikoptas, we made sure you have both pitch and roll gimbal options* (memory limits apply in current bloated code - you either choose GPS or you choose gimbal - not both at present code bloat A0 = pitch  ;  A1 = roll (this is for servo gimbals only - for Brushless gimbals you need a special brushless gimbal controller called an Alexmos HERE)
  8. No extra charge for the Hero software - MultiWiiCopter software is Open Source - FREE - AIR uses specifically modified code for its sensors and features which are activated by code - make any changes you wish but realise that in doing so you assume 100% responsibility for such changes.
  9. The LED GND Triggers lead works to drive to GND the Andromeda - see code note below to reverse it
  10. If required you can attach the OLED screen to the GPS port to tune the PARIS Sirius Air.  Requires code to be active.
  11. Please note that PIDS for the v2 HERO AIR with 32u4/3050 gyro/BMA280Acc are different (higher) compared to PARIS AIR v1
Design Team ; Alouette III and EE Timecop.  I have to thank TimeCop for his unequalled EE ability and total professional conduct - Timecop is the best multicopter EE out there, an independent, original thinking person and a total legend in the open source world. He's widely mis-understood - most brilliant independent people are vilified unfairly. Whats new..

FPV Features 

HERO MODE - this is otherwise known as "ACRO" mode, short for Acrobatic - in this mode only gyros are active - photographers will say they are not interested in acrobatics - well neither are we, for the sake of it - but like judo or karate you eventually realise why the master is forcing you to learn skills - master this mode and you will have a "core" skill for life called hand-to-eye-coordination - non-pilots who fly is other "modes" like GPS/Atti will never progress even after years - and will form a dependency on artificial "help" - if you master HERO mode at the beginning of your days then you will dominate these pilots in every possible way - respect and results will follow.  Use this ACRO mode to do Flips over soft long grass.

ARM - we don don't recommend arm by switch - reason - it's a waste of 4 possible switch positions other than off - if you have 2*3 ways switches - use them for other stuff below. We recommend to arm with sticks, motor stop at arm then trim up using throttle trim - this will give you gyro lock in all mode from 100% to 0% and prevent accidental mid air dis-arming 

ANGLE Mode - this activates the Accelerometer - self levelling mode - (was called LEVEL or ACC before) - its a beginner mode "L" plate mode used for hovering - we don't recommend you Fly in this mode - its designed for hovering directly above your position - where it's otherwise difficult to see small attitude changes.  Its useful for FPV take off and land IF your experienced - do not use this for your first noob maiden take off as it confuse you - the acc is sensitive to 0.1° tilt and will rev the props on the downhill side like buggery until its gets its 0.1° offset sorted - its a required mode for RTH

HORIZON Mode - this is a cool new mode - when the cyclic stick is near the centre the Acc is activated - but when you want to fly fast forward or even do more aggressive high-bank angled ops - then at FSD (full scale stick deflection) its gyros only - love this new mode!  Again don't always fly in Horizon mode - it makes your brain lazy.  For every 4 batteries on HORIZ mode - do one battery 100% in ACRO mode too.

BARO - The Baro sensor is safely positioned away from light, in the dark at the bottom of the PCB - If you keen you can also cover the front USB with a small piece of black nitto tape to prevent drizzle or rain getting in :)   by  placing BARO underneath and inside prevents erroneous barometric pressure waves from speed or wind and also blocks lights entering the BARO - use this BARO mode when at 505 in the hover, to hold Altitude as a park brake - 2.2 is the first open source release of this code to combine AccZ (G readings) with BARO info and provides a 300mm height hold in a well setup scarab.  We use it for parking and RTH - obviously we can fly better than any baro itself so we don't use it to hover - use throttle for that.  Its great for high ALT parking at a longer distance as well. DO NOT turn BARO on until you are first established in the hover at 50% throttle - then turn BARO on in the hover  - (never attempt to use BARO before takeoff or general stick flying !! as the MWC software is not designed to control the engines unless you start the BARO in the hover first at 50% - it is like a PARK BRAKE - again when ready to resume flying, then turn BARO off such as descending - or climbing or returning to land etc)

MAG - (the MAG sensor is located on the GPS board to keep it away from the centre of the aircraft - not included inside the body of the AIR itself - separate product = PARIS GPS mag HERE ) - Compass or heading lock - be sure you have 1500 setup as the RC Tx Rudder - then when the rudder or yaw stick is centred - engage MAG - this will lock the heading.  We don't recommend flying around with MAG on - reason - MAG will lock out if bank angle exceeds 20°.  Mag is useful for doing towering climbs or descents where you are flat - and trying to shoot facing one direction - be sure to tune your airframe (by engine inclination) so you have zero latent yaw.

GPS RTH HOME - very useful - (requires GPS/External MAG - not included - be coded and connected - setup MAG/ANGLE and GPS home on the same switch position - BARO also if you prefer but only activate after take off when hovering or cruising - then use RTH to fly home - will return to the position where it was last armed - does NOT control throttle so be sure to use enough power to fly/hover.  Importantly PARIS offers hared control (IMU and Pilot) during the return to home phase - it is NOT fully autonomous - this is a good thing as it allows the pilot to make inputs to avoid obstacles - without having to do a full manual reversion.paris-air-v2-gps-returning-home.jpg

HEADFREE and HEADADJ  - it is for pro's doing long range LOS or noobs who have no orientation skill. - it uses the MAG to provide orientation based on ARMED orientation.  Headfree is forever linked to ARMED and HEADADJ to time when switch is flicked ON.

GPS HOLD - Acts like a Parking Brake - Do not attempt to take off in GPS modes, or even to fly around in GPS modes - For AIR GPS use -> Before take off look for the GPS sats acquired signal (solid blue LED on GPS with fast 3/sec green LED on GPS) Take off with GPS OFF - then Use GPS hold when established in a hover position, Make sure MAG and ANGLE are active using the check-boxes(white), with ANGLE hold MODE (then tune the LEVEL condition by Acc trimming or stick banging) - so GPS Hold is used like a handbrake - i.e. get in the position you want then flick the switch for PH when established at 50% throttle -  the best way is to combine it with BARO/MAG/ANGLE in the GUI column.  GPS home is recorded each time you land and re-arm provided there are sufficient GPS Sats visible - we generally use GPS return Home a lot - and never use GPS hold

PARIS Sirius™ Air board - in full metal jacket - 3 Axis gyro, 3 Axis Acc and BARO - with onboard Micro USB 

  • 6 way Rx RC leads connector 170mm ; Works with any RC Rx with 6 channels
  • Pre-flashed Sketch Software optimised - installed tested and calibrated version 2.3 (What new in 2.2->2.3 Read HERE)

The D4R-II from FrSky is a favourite Rx for C-PPM enabled (set 27ms) mini Quad controllers like our Aussie PARIS v2 Hero. or HERO•32 bit naze becuase it is compact, has 1 wire 8 channels ; and can easily be connected to the voltage sensor FBVS-01 and the Variometer SPort with our D4R-II hack below (without any HUB needed!)

  • Excludes USB Micro cable - these sold in store (same as dji naza cable)
  • Excludes Sbus->CPPM cable HERE for Receivers like X8R or X4R
  • Excludes i2c PARIS GPS/MAG - info for GPS use and setup is HERE
  • Excludes Rc Radio Receiver 6Ch - or CPPM such as TFR4(For Futaba users) ; or FrSky D4R-II (for Taranis Users) - the best solution for a mini-Quad is the C-PPM single wire with FrSky D4R-II with a Taranis
  • NOTENever connect or disconnect ESC or SERVO pins while PARIS is powered up & Live or while ESC are live !! - if you reverse connect or connect pin high you can permanently damage the PARIS CPU outputs  - always connect all servos/ESC with power off - only connect 5v to the PARIS last - and be sure NOT to reverse the polarity.  Make sure your uBEC can provide sufficient amps for the Gimbal servos.
Software is Pre-Installed and tested with pre-loaded firmware v2.3 (be sure not to use the older 2.2 GUI ! - must be GUI 2.3!)
Multiwiicopter software is open source - you DONT have to know anything about it - however best don't alter it if you do don't 100% understand what the code "comments" do - Its a step-back for you to immediately load  code as soon as you get the AIR - best don't do that because its "ready to go" (usually it's a PC problem you have, its NOT the AIR) - the firmware has to be 100% perfect to be safe - The PARIS Air comes pre-programmed and individually tested  - the last thing to do is assume the product is faulty as soon as it arrives (it's working perfectly - we checked it before shipping it out) - Chances are YOU have not powered the GPS by 5v etc ! so assume that you are at fault - that you have assumed something - or skipped something out - all you have to do is set your centre your RC radio Tx points to 1500 - your lows to <1100 and highs to >1900 - Then load up the Free PC/MAC v2.3 GUI , and confirm you understand which "mode" you're in from the GREEN bars in the GUI.  Compare photos here on this page to your install before you connect power or add props - study these photos  - emulate what you see.  Most people contact us asking questions and we generally just direct them back to the relevant photo on this page.  ... for example "I cant find anywhere how to connect my RC receiver?"- so here on this page is a photo showing the connections to RC receivers ; or "I don't understand where to connect the black wire?" - its the GND trigger wire and goes to Andromeda - see Andromeda page .     Your board comes preloaded with v2.3  - if you alter the code you are taking 100% responsibility for the control of the aircraft safety at that point - many of the default setting will overwrite the PARIS code - including:
  • the Failsafe (We disable this and use the Tx failsafe) ; and
  • the motorstop functions (We use this function with Tx throttle trim) ; and
  • the servo travel (We use 1100/1500/1900 in code) ; and
  • the gimbal settings
  • the eeprom PIDs tuning
  • the memory saving functions
Attached hardware - This MultiWiicopter.com website contains itemised-wiki product information for each part attached to a PARIS AIR - so if you have a question about an "ESC getting hot" - go to that ESC page ;  and search for the word "hot" relating to that ESC product - i.e.  - on the relevant parts page on this website. There you will find info on that drill-down topic page.
The PARIS AIR support forum is here http://www.rcgroups.com/forums/showthread.php?t=1420778
Sign up - just post a picture of your setup/wiring/connections and your GUI screen capture & ask a question on the FORUM - people will help you in a few hours (if not post a picture and ask again to clarify) - thank them - make friends - (don't be a forum lurker loner - open source is built by team work) PARIS AIR is an Open Source product and this means support is NOT provided by us for the software - Most people need little or no support - but some people are never going to be able to understand it because they don't have the aptitude. Period.
For noob install issues see Q&A at bottom of this page - scroll down

Before connecting ESCs - Important Notes for power - WARNING
PARIS AIR v2 Supply voltage is 5.0v max - this power is supplied by the red wire of the ESC's - i.e. you have to connect your LiPo to the ESCs to power all functions ->ESC(s) feed 5v to PARIS AIR and the Futaba/Taranis Rx ; the USB 5v only powers the CPU , not the GPS or the RX , nor an oLED !  - GPS 5v supply comes from the ESC 5v BECs onboard each ESC - via the red wire(s) - leave at least one red ESC wire(s) connected.  Never attach any 6v Heli uBEC - Never attach any 7.4Heli uBEC - Never use a servo targeted 5.4v uBEC - you will blow/smoke the GPS and the PARIS AIR or get suspect ops.  NEVER attach any LiPo direct - No 3S 12v power to PARIS ; No 4S 16v power is ever connected to any part of the board! Only connect 5.0->5.1v maximum - this comes from one ESC  ; or disconnect all red wires & USE the approved uBEC here.  Never connect or disconnect LIVE ESC wires from a powered up PARIS ! Turn everything OFF first - regret is permanent - be safe - power off.

Connecting ESCs

Before connecting the ESC make sure LiPo Power = off !  Connect the 4 ESC control wires with the white control wire at the top - The Red wire from the CarbonBird ESC will supply 5v. As per photo below.  Then connect 4 ESCs to power-distribution-lead. CHECK Props = OFF ; Then connect main LiPo (keep the Quad still for 10secs) - finally connect USB last
pins-paris-sirius-air-images-9752.jpg paris-air-quadx.jpgparis-air-triicopter.jpg
Connecting Gimbal drivers (for servo gimbals only)
Connect  A0->pitch  ;  A1->roll servo
Mounting with gel tape
Use only the supplied GEL based tape is the small thin strips provided - do NOT add extra tape - do not use other DIY tapes or 3m forum here-say method methods to attach it - do NOT use 3M white foam tape specifically because it's rubbish for vibration transfer - Use only the supplied green Gel-foam tape any apply only as shown in these photos on this page in the geometric centre of the craft.  Locate the Air with the USB arrow pointing forward and in the dead centre of your Quad/Tricopter as close as possible to the C of G
Calibrate your Tx 
RC Tx have small errors in centre points 1500 which can easily be corrected, as a PC/Mac running the MW23 UI reveals the error.  Its possible to calibrate a PARIS with the oLED screen if oLED code is active (i.e. you ordered QuadX with no GPS).  If you don't have an OLED then Connect via USB Micro to your mac/pc (see bottom of page for PC issues) - (for Mac OSX close the keyboard dialogue - red dot - if it appears as its not a keyboard) Also connect one ESC with no motor to provide 5v for the Rx and or GPS/oLED if connected.  Download the MultiWii GUI v2.3 - here - install it and run the App "MultiWiiConf2.3" - click on the USB comms port which represents the AIR. Press start.  You will see data bottom left for the sensors which are coded active and top-right your Rc Rx channels data - alter your Tx mid-points to give 1500.  Alter your end-points in the Tx to be lows less than <1100 and high >1900 - re-check midpoint still 1500 - check for reversals; blue bars should move the same way as the sticks - Throttle and Elev the same way with the antenna facing right.    Select your GUI boxes.
MAG Compass & GPS install (this applies if ordered with a GPS - otherwise if added later, then re-load new GPS/MAG version of code first)
The MAG/compass and GPS require 5v power from the ESC to function (not USB power which only powers the CPU).  Make sure you fully build your quad - have everything turned on and the LiPo is position. Make sure the PARIS MAG/GPS is 80mm away from other devices.  Props off - TX on - Multicopter final checks for all wires connected correctly - white ESC wires are at the top - all ESCs are synchronised and learning curves done - not wires shorted to airframe - place the Quad 100% level - don't move it - Connect main LiPo to the ESC -> this will power up the AIR - then connect USB last using our 2m USB cable - sold separately (not included) - then start GUI - Then press CALIB_MAG - led will flash rapidly for 30secs - rotate the entire multicopter 360° XYZ (keep it 900mm from PC, phones, metal, iron etc - and 5m from cars toolboxes or metal wall frames) - When the LED stops blinking the MAG lines will all jump a bit on the graph - this is the new aircraft calibration.  Then check the GUI shows the airframe 100% level as actually 100% level - otherwise set it down 100% level and press CALIB_ACC - wait 6 secs - the GUI will reset and should show for ACC values of 0/0/512 approx.
Hand Maiden
Always do a hand maiden - hold the Quad safely by the centre and fly it in your firmly gripped hand to check everything - it's soooo lame to watch people tipping over aircraft on a maiden because they are afraid of it and have it sitting on the ground - hold it ! Wear safety glasses and gloves by all means - but just like a mud crab - if you hold it correctly it cannot hurt you.  Common noob mistake is to put the wrong engine ESC connector on the wrong pins - this causes the quad to strongly flip in roll or pitch ; check first !  Make sure no vibration is present.  If you feel vibrations in your hand they can get to the IMU & GoPro.  Re-check the balance of your props and motors and the that you did not man-bend your collects.  if the copter wants to tilt over really hard - chance are you have the engine ESC in the wrong slots.
after doing the successful hand maiden(above) - comes the maiden. Don't maiden in front of crowds of office workers or near people! go to a remote field.  Make sure all advanced nav/baro/mag/RTH/PH modes are "OFF" and all centres are 1500 in GUI - Take off and go up to 2m - don't try to hover at 50mm - the ground cushion effect will cause you to skate all over the place - even expert pilots avoid this zone - go up to 2m and hover there in free air in an open field away from all people... check for any residual yaw - note it - then land and tilt the engines to give a "zero" yaw result -  If you experience random twitch behaviour - land ; re-balance your props and motors properly - check that you have not bend any collets? -  the Hero v2 is highly resistant to vibration however its the most common cause of all known issues - Go to the GUI and check for random I2C errors or spikes in the GUI live trace - check the data in GUI - each sensors displays it's data for you to see).)   If you don't have prop balancing skills or don't like prop balancing - Don't get into multicopters at all.  The maiden flight usually involves hovering tail-in and checking all controls are operating well XYZ and then progressing to figure 8 moves and eventually nose-in moves.  After landing check all motors temps are "warm" only - and all ESC are normal temp (not so hot you cannot hold your finger on them).  
Quad size vs LPF
Small quads run much higher RPMs, & produce higher resonance Frequencies, and their Low Pass Filter (LFP) can be set much higher at OOF or 98hz or 42hz - larger Quads need to use a 20Hz LPF as their resonce freq is lower.  The default LPF covers most noob-vibration issues - if your props and motors are all properly balanced you can turn off (comment out) the LPF - but its set to 20Hz to cover beginners and the odd nick in a prop here or there, leading to an airframe vibration.  This is especial true as the AIR case removes a large amount of vibration by inertial mass dampening.  As always we recommend you balance your motors and props regularly and check them.
Coding notes
For 32u4 select "Leonardo" in Arduino  -  you can reverse the LED pin status for the GND trigger wire by commenting IN this line 

/*********************** Promicro version related ****************************/
/* Inverted status LED for Promicro ver 10 */
#define PROMICRO10

 For Triikopta +GPS ->  we are now have a code reduction to allow Triikopta + GPS to function together in the memory space of the 32u4 CPU (headfree code is disabled saving 400bytes) 

For Triikopta - be sure to connect a C1 CAP to the spare A0 or A1 pin to prevent brown out from servo peak amp loads !  C1 CAP is a great anti-brown out device on any multicopter for a few $

Question : How do i adjust PIDs - Is there a Bluetooth for PARIS Sirius AIR Hero v2 ?  Answer = BT is serial device - so NO the V2 does not have a spare serial port as the serial port is pre-connected to the USB direct internaly CPU -> USB 32u8 - so for PIDs Best, if you have a GPS installed (coded GPS) to use either OTG Plug for direct android adjustment of PIDs ; or use the oLED (must be coded oLED default coding ie ordered with no GPS) and adjust PIDS via sticks command on the oLED page here

Question - I am having PC Issues on Win7 or Win8 - cannot seem to connect to PARIS AIR?
This is usually failure to load the correct usb drivers in WINDOWS - so here is the noobs guide to your PC setup
Use the Micro USB cable connector sold HERE - connect AIR to your PC.  If you have a GPS connect 5v (ESC when powered up produces 5v) - DO NOT HAVE ANY PROPS installed !
  1. Download and Install Arduino 1.0.6 (reason is it includes usb drivers for Leonardo even if you never use Arduino) - 
     - install arduino - restart
  2. Follow the instructions on this link below, on how to make sure your Win Device Manager is using the correct USB drivers for Arduino Leonardo
  3. check that you see the comm port number for Leonardo - make a note of it - comm number is different on each PC because Windows creates "virtual Ports" each time - so, ours is comm15 - most likely your comm number will be Comm3 or such

  4. Download the JAVA GUI v2.3 here https://www.carbonbird.com/product_images/pdf/MultiWiiConf_23_Paris.zip (NO NOT USE 2.4)
  5. UnZip it to desktop -> open the folder MultiWiiConf_Paris and sub-folder called application.windows32 ->double click on the JAVA  app called ->MultiWiiConf (make sure to use 32bit even if your PC is 64bit)
  6. If MultiWiiConf does not run at all then you may need to install JAVA on your PC - security setting may stop you - you are responsible for security - your decision http://java.com/en/download/index.jsp
  7. For Apple Mac OSX Yosemite you will need to install the older Java 6 SE here in order to get the GUI to run, and also to run Arduino 1.0.6 too for that matter - Java 6 works fine after this is done - We use Yosemite, El Capitan and Sierra OSX with java 6 SE ourselves (note - JAVA 6 SE does not work with HIGH-Sierra yet)
  8. Now click on the exact same Comm port (in this example Comm15-Leonardo) -> press START - -> you will see the data lines logging data from the Sirius sensors and the green LED will blink fast  (if you have a GPS connected - be sure to power the AIR with 5v first, because USB only powers the AIR not the GPS) .   GPS does not work inside buildings - if you see an i2C error of "3" its working correctly (this is because the GPS starts up a little slower than the 32u8CPU does)  - if you see I2C errors then your GPS is not connected (wires are not making contact) or not powered up - NEVER CONNECT ESC unless all power is off - Make sure the white ESC wires are at the top, then power up - always power the cycle with USB removed - for GPS information see https://www.carbonbird.com/products/gps-multiwiicopter
  9. The AIR board is already programmed, checked, calibrated and PIDS are set - don't change anything randomly
  10. If things don't appear to work on your PC its 99.9% most likely a PC problem - Do not assume the AIR is faulty - Do not reload raw code! stay calm ... start again ...  - once you get the drivers working, study the gui - try to understand what GUI data it is telling you - do not change boxes or pids without knowledge.
  11. The main reason to open the JAVA GUI is to confirm you RC midpoints 1500 and endpoints 1095/1905 - and check your RC switches do what you expect.  If you purchased your Futaba radio from us - we already did this.
  12. press STOP -> CLOSE COMM 
Question - how to replace or update to a new Master Sketch firmware file to PARIS Sirius™ Hero v2 flight controller? - If you wish to change the platform/drone type or change settings like add a GPS (i.e. platform = Trii to Quad) and you are 100% confident the sketch file you are about to load is correct (this is serious) - then the way to change the firmware is as follows (wiping and replacing firmware Sketch - at your own risk and duty of care) - Sketches cannot be read back out of the Leonardo CPU - so keep a folder on your PC/Mac and each time you update a Sketch, make a copy and keep the original saved in another folder. Folders must have the same name as the main .ino file inside.
  1. take screen shots of ALL your old settings - as they will be lost in the update proces ; then connect USB (requires drivers above)
  2. use Arduino 1.0.6 to open the new sketch (in each downloaded Sketch folder you see 28 files - select the file with the longest name such as MultiWii23_AIRv2_14_TriiKopta_oLED.ino for example and open it from 106, that file will open on the first "tab" -  then go to the 24th tab(or click the triangle on the top right to see a drop down list if your screen is small) ,  then comment out Tricopter // and comment in Quad (remove the 2 //) - you must be sure the sketch commenting/code is correct 100% -  while in the config.h tab,  check all code "comments" - ie the active lines are in black.
  3. select menu tools/board type = Arduino Leonardo
  4. select the correct USB port for the PARISv5 such as COMM3 (will be different for any PC or MAC) serial-port-for-paris-v5.jpg - if not sure simply pull out the USB from the AIR - then check the 106 Port menu again to see what dissapeared from the list - then re-connect the USB to what Port is added now to the list.
  5. first upload the file "clear eeprom" - menu/files/examples/eeprom/ then UPLOAD - (you will now have 2 windows open) upload the clear eeprom sketch twice - this flushes out old settings completely wiping the controller - be aware.
  6. Select the other panel/window with the new Sketch -  upload this new 100% correct sketch ; UPLOAD (keep a record of it somewhere as the sketch CANNOT be read back out!)
  7. Quit 106 - launch the MW23 GUI and redo the CALIB_ACC with the Paris IMU 0.00° level
  8. the GUI runs under JAVA 6 - so for Apple Mac OSX  you will need to install the older Java 6 here in order to get the GUI to run, and also to run Arduino 1.0.6 too for that matter - Java 6 works fine after this is done - We use El Capetain OSX with java 6 ourselves. For PC ensure your JAVA security is suitable - security settings are your decision (and your risk from OTHER 3rd party invasion - we never have any issues but we don't ever go to risky sites and we run full virus protection as well)

Question - My GUI wont work - is that a JAVA issue on PC?  Answer = Yes MultiWiiConf uses JAVA and some latest verisons of JAVA wont work in some PCs - install JAVA 6 or 7 from HERE - then restart your PC/Mac - connect the PARIs Micro USB to your PC USB . The 32 bit GUI (Use the 32bit version even on 64bit PC) requires Java is installed and running - recently Mac OSX has removed java - we use and run it under Windows 7 and also Mac OSX Yosemite with no problems - be aware that JAVA security is your risk on your PC, be sure to run a full Virus blocking agent on windows such as http://www.f-prot.com/ -  For Apple Mac OSX Yosemite you will need to install the older Java 6 here in order to get the GUI to run, and also to run Arduino 1.0.6 too for that matter - Java 6 works fine after this is done - We use Yosemite OSX with java 6 ourselves - For PC users experiencing JAVA setup problems, you can choose to use the alternate WinGUI here (Win GUI does not require JAVA.) however we dont like  WinGUI so much as its a tab-fest and fails to use modern HD monitor space effectively, leaving you clicking endlessly through tabs, very retro.

Question - Cannot ARM my PARIS Sirius AIR?  Answer a) check Rc limits in GUI = See item 10. above QuestionAnswer RC travel limits <1100/1500/>1900 for Non SimonK ESC Throttle Channel or <1064/1464>1864 SimonK ESC - If your RC travel is set correctly ; then b) make sure you have navigation turned off - this means BARO=OFF ; GPS = OFF ; RTH =OFF
when disarmed the GREEN LED is ON - when armed the Green LED is OFF. If you connect external LED via the GND trigger they work in opposite phase to this, so the aircraft LEDS will be on when armed (if connected via the black lead to GND)

Question -  All my ESC's beep all the time non stop?
ESC will beep to WARN you the THROTTLE is not at ZERO - the ESC can be taught (as a group of 4 or 6 or 8 ESC) the correct ZERO point in a process called "ESC learning throttle ranges" - see Noobs Guide - Pg11/12
Noobs sometimes assume the throttle is at ZERO when its actually at FULL -> 1900+ - so when connected to the GUI - you should see a value of 1095 at low throttle position; You must redo the throttle learning after first setting the Rx Throttle channel to 1085-1095uSec.    Beeping ESC/motors can also happen on a PARIS v5r3 if your main LiPo in not yet connected and you only have USB connected - but the PARIS AIR is powered separately so USB power does NOT pass to the Rx or the ESCs.
Question - My Receiver and GPS have no power? Why?
Its' important that you understand the different voltages in play 1. Engines 12v->16.8v2. FPV gear 12.0v3. Paris Sirius™ AIR GPS, RCRx 5.0v ; 4. USB 5.0v power to CPU only- So there are 3 main DC buses on your Multicopter (+ USB if connected) - You must learn where/how power flows.  Your PC USB carries a limited 5v supply - So PC USB (if connected) powers only the CPU and sensors (Not the GPS/Mag nor the Receiver nor the ESCs - OK so CPU only). The Main LiPo Cell, the big black LiPo carries 3S or 4S - so somewhere between 12v-16.8v and this goes direct to the Power Distribution Lead PDL (or Voltair depending on your Scarab) - the PDL feeds this 16.8v out to each of the ESCs.  The ESCs each have a 5v Linear voltage reg in them making a safe 5.0v for the GPS/Mag and the Receiver via the red wires.  Full LiPo raw voltage Power also goes to the ANDROMEDA PDL - Andromeda has 2*12v FPV regulators in it - mark "FPV" ; so Devices like FPV camera and FPV Video Tx need 12v. If your not sure use a DMM to measure voltage.  NEVER connect anything at random.  Never connect wires reversed polarity (red = +ve and Black = -ve) In fact we teach never to blindly push any connectors together - slow down, check red=red ; check black=black ; confirm voltage bus is correct - props are off - Check Tx is on and all switches set and safe - then power up the copter.  Never pull any wire by the wire , grip the connector and rock it slightly as you pull or push it! Use lanolin or  Inox or Corrosion-X or Deoxit Gold on all connectors.  Never pull ESC connectors off the AIR while power is live ! Never push a live ESC connector onto PARIS - ! 
Question - I can see increasing I2C errors in the GUI?
Usually this means that you have coded ; or purchased a GPS coded AIR - but you have either a) Not powered up the GPS with 5v first (don't connect usb first ; don't leave USB connected if cycling power) ; or b) not attached the GPS ; or attached a GPS to an AIR coded for oLED.  MultiWii software cannot tell if a device is connected or not - but the software expects to see GPS data when requested - and if the GPS is either OFF or disconnected when the code (SKETCH) says GPS is enabled - then it will produce a stream of I2C error - connect & power the GPS via 5v BEC first - if a GPS is fitted it should show errors "3" which is correct and working well.
Question - How do I know what modes I am in?
Noobs must familiarise themselves with switches on their RC Radio TX - by connecting the copter to USB and the PC GUI interface you can see on the PC screen (or Mac) the effect switches are having on modes - the AUX1 and AUX2 blue bars will move to shown LOW/MED/HIGH and the corresponding L/M/H "boxes" ticked (click the upper-left quadrant of the small box) being WHITE (press WRITE to save) show the Modes turning green.  Remember we don't recommend any modes are on for your hand maiden and first flight maiden - turn all modes off and fly with 3 AXIS - gyros only (called HERO mode - or acro mode) - if you don't have any prior experience use a FLIGHT SIM first
2nd answer - You can also see what modes you're in with a oLED connected - but you cannot have and oLED and GPS together - its either one, or the other - and each requires different firmware hardcoded into AIR - Important point !!
QuestionFlight Modes -   ACRO vs Auto LEVEL - I want to know when and how to use modes?
Some Noobs want to use their wallet to buy their way to a full auto-pilot and have their first aircraft fully autonomous - so buying a "better" autopilot for their first copter - or get GPS so that GPS controls the aircraft for them - I understand a photographer just wants to shoot - but unfortunately putting a vehicle up in the sky is a big responsibility which rests on the shoulders of people - we call these people pilots - wether they are on the ground or up in the craft - so we STRONGLY advise you to get stick skills first.  Many NAZA/WookM or Wii pilots who "form a dependancy" on autopilots damage their own progress and NEVER EVER become "Pilots" they are like drug addicts addicted to robotic-autopilots - and don't fool anybody except themselves
the real JOY of the multiwiicopter PARIS ACRO system is the amazing combination of smooth 100% control with full stability only PARIS offers - hard to explain - it's just amazing how the basic gyros only flight mode - called ACRO - handles really well - its far more satisfying than robotic-interfering autopilot level modes - in these other highly automated "modes" - especially those designed to grow market share, you feel like a cab passenger in New York - you can basically direct the Cab to go where you want but your in no doubt that your NOT the driver - Well with Multiwiicopter hardware/software it's the opposite - in ACRO mode (ACRO = fail name - should be called AWESOME mode or Real Pilot HERO mode) you have absolute and complete control - yet its smooth predictable and stable - MultiWii HERO mode is much crisper than DJI manual mode.  ALL the team pilots at MultiWiicopter.com fly in ACRO (HERO) mode - almost all the time.  All professional stick men - "PILOTS" learn to fly - for real.  All multicopter fly better in GYRO mode with the BARO and the ACC disabled.  Beginners and auto-pilot addicts use modes all the time. 
OK - what to do ? First off  fly Mode 2 - I am a real Helicopter pilot/instructor - so the other modes are like weird to me - sorry  mode 1 guys - but as per a real Heli Pilot   - right hand controls X&Y and left hand controls Z axis
Question - How do you do Transmitter set-up
I set on the switch above throttle FUTABA SB (or the right stick on some Tx) this switch controls ACRO/LEVEL - down is ACRO - up is LEVEL on.
Then on 3 position stitch on right side FUTABA SC - up off/mid MAGon/ down/MAG & BARO on (if GPS is fitted = up off/MIDPH/Down RTH)
I fly 95% in ACRO - I use LEVEL mode only for
  • High hover parking while looking at something (my ground station LCD)
  • I use LEVEL mode for Take-off on FPV video goggles - FPV - when in sloping or patterned area with no obvious level horizon line  - first 10m climb out - then switch back to ACRO pilot mode
  • Landing on FPV Goggles - FPV - last 10m to touch down
  • Crash recovery - if lost orientation - crash recovery panic is a) power up 70% b)hit switch above LEVEL on c)release right stick to centre it
I use MAG for level hover heading lock - MAG does not work when tilted more than 20° - erratic readings - don't go flying around at high bank angles in MAG locked mode. - Calibrating a MAG means press the button and then rotating the Quad XYZ 360° in 30 secs
I use BARO - for high hover parking at 100 feet up above my head  (in calm wind - otherwise it will go downwind) - its not ultra sonic - use your eyes/brain/hands to hover the aircraft - you don't need an auto pilot for this - get more stick time and get your skills developed.
GPS - For PARIS GPS we use this for Return to Home - if your under a lot of pressure and too far away to establish orientation - sun in your eyes etc - flick RTH on - As soon as it get close and spins around - turn RTH OFF
Question - I have flown a NAZA - Is this better than a NAZA?  Answer = Holistically MikroKopter & DJI approaches drones totally differently and assumes you never wish to :- a) learn to be a pilot b) actually fly it fully yourself c) will go for the easy option me-airborne-today option (even if the long term outcome is negative skill growth and risk high) DJI is founded by people who are not even pilots (1 marketer, 1 engineer) - This is evidenced by dji disabling access to manual mode by default. NAZA phantom only comes with GPS and ATTi (manual mode is hidden) - with phantoms now flying 100% with GPS before takeoff (with fly away consequences).  Unlike AIR which has a very true and crisp manual mode, NAZA phantom in manual mode feels really un-responsive/bad when used(they NEVER expect you to be able to use it).   On the other side of the approach to drones is PARIS AIR using MultiWii open source code design by pilots, for pilots - This software assumes you want to learn lots of new things and you want to develop pilot Skills - starting with a flight-SIM Simulator and really learning to be a pilot of RC (equates to not needing the floaty wings to swim in the pool- look mum i am swimming with float wings - no thats not swimming - if they pop you will drown)  - if you think you were flying your NAZA - sorry but you were not - NaZA flies itself and the tea Lady can do what you do, nothin learnt=nothin gained  (we accept some people don't want to fly and that is why we offer those customers the naza)- in Naza / Phantom Atti mode still only gives you partial indirect control of motors and height holding is not even controlled by you, nor is vector compensation in turns - so naza owners usually struggle to learn anything post-naza and in fact crash when try to fly a full pilot multicopter gyros only - A naza operator over a year will loose any skills they previously had to be RC pilots.  NAZA pilots don't even understand RC setup as it is hidden from them.  We don't recommend any NAZA operator assume he can fly a PARIS - sorry - pilot skills development takes time and effort...  your decision to become a pilot or stay an operator, but past experience is  ;easy road ≠ best road ; and naza is never ever intended to develop any skills in the pilot dept - PARIS is the opposite. Once you really learn to fly - you have something far more valuable - something you can depend on - your human skill set.   Common mistaken assumptions from NAZA users 1) DO NOT try to set BARO on before takeoff - the AIR will NOT ARM with BARO on - baro is a hover park brake system - not a fly around every-where system like naza 2)Do not try to take of or fly in GPS modes or RTH mode - use Horizon mode or (get the SIM) learn ACRO mode
Question - How do i reverse the Tail Servo on my Tricopter or Avatar? You must not use the gimbal sticks REV menu the Tx to do this  ie not a Tx setting ; as the GYRO/ACC itself must be reversed - so the direction of turn of a Tricopter Tail servo is controlled in the GUI for the AIR v2
  1. to reverse the direction of Tricopter servo ; ensure power is LiPo and all ESC connect M1-M3 ; servo in M4  - Props OFF
  2. Launch MUltiWiiConf GUI (java app) on your Mac or PC
  3. Click USB modem (Mac) or Comm 4 (PC) ; click START
  4. Click Settings TAB at the top ; click READ ; Click Servo at the TOP ; click SERVO at mid ; click GOLIVE ;
  5. The small grey yaw box "change Gyro/Acc direction ; click it to change from grey to White ; click SAVE
  6. the tail gyro is now reversed. 

You can also set the Aux 2 Channel to "trim" the perfect hover position - drag the light blue bar "1500" all the way to the left with mouse down and back to the right (still holding your mouse down ) until it changes to AUX2 ; SAVE

Using the Tx sticks to operate the PARIS Hero v2 (mode 2)

Set the Throttle to OFF/LOW (and check the GUI 2.3 to be sure your RC radio is not reversed either) - After connecting the LiPo - The ESCs will beep to indicate they are powered but not armed  -ESC's cannot arm on power-up with PARIS AIR.  The embedded software prevents this and requires you arm with a stick combination below   The blue LED comes on (steady) on the CPU board showing the board has power.  After connecting the LiPo (or USB) the green CPU LED will flash for 5 secs then go OUT   If the LED blinks green (fast) but won't stop blinking - then the Rx is not powered by 5v (an Rx cannot get  PWR from USB! It must be powered by 5v from at least one BEC).If the green LED still blinks green (fast) but won't stop blinking -then the Rx is not connected to the correct PARIS THRO pin correctly.  The ESCs cannot calibrate as a multi-engine-group because the default state of the CPU->ESC is Dis-armed for all engines.  You need to calibrate ESC throttle-learning range as a separate exercise -below
If the ESC's beep-non-stop then they are not connected to the PARIS board ESC pins correctly (upside down) or the Rx is not powered/ connected or the Rx/PARIS sees you do not have your throttle to zero. Check the Throttle output via the GUI.
If your copter goes out of radio-range it may cause harm - if still powered - Take the precaution to program in the FAILSAFE condition to protect people/property.  Do not skip this step.
Bind your failsafe (Read your Radio manual - FAILSAFE) on the Tx with power/Throttle DESCEND failsafe condition.  You might decide to set the failsafe power to 40% throttle so the aircraft descends in a controlled descent - recommended if understood - For Example on FrSky - set sticks as above (or THRO to 40%) - then Press the Rx button - 2 green flashes on the Rx itself - done.    Failsafe can also be set in MultiWii Software (this option is NOT recommended - Use only for ultra basic or legacy Tx's like turnigy 9x  - if your Tx has failsafe Like all JR/Futaba/FrSky- use hardware failsafe in the Rx). When you turn your Tx OFF in a test the Failsafe   -  should return the Copter to level and min-throttle - 
NOTE : If you use a 33%-40% power (controlled descent setting) be aware that if you switch your radio off while the PARIS armed - then you will initiate a 1/3 powered condition!  This is why the Radio must go "on" first , and "off" last.
You must understand this concept fully and realise the word failsafe - does not mean you can skip this step - sorry - you still need to understand the consequences of your chosen "failsafe" condition - and You will be deciding what YOUR Radio "pre-set" will do when it cannot receive a signal.  You are still the Pilot in command - YOU are responsible to decide how you will handle failsafe above. So set all your chosen stick positions and program the Rx.  Then test it in the GUI. Turn the radio off and make sure the GUI shows the RC Rx goes to what you expect it to.
Arming - Wear eye protection - Learn to recognise that your multiWiiCopter is ARMED.   In MultiWii 2.3 or later there are several safety no-arm "blockers" (for safety)- you cannot ARM if tilted ; you cannot arm if BARO is on ; you cannot arm if GPS is on.   You cannot arm if you were moving/carrying the PARIS AIR within 20 secs after connecting the main LiPo - Keep the copter perfectly still for 10 secs after connecting the LiPo to allow the gyro self-calibration to complete.  So to ARM -> keep throttle below 1100 uSEC (off) then Hold right Yaw (or right cyclic) for 1 sec (>1900) - you will see the external strip LEDs come on (if fitted via the ground trigger) - stays on SOLID (the internal LED of PARIS AIR is opposite so it will go off if armed)  - If the andromeda LEDs does not come on and stay on solid - then increase YAW travel on the Tx to 110% (see Transmitter Calibration procedure - above top) - or Check the THRO is not actually reversed by mistake (Futaba) - USE THE PC GUI it will reveal your actual numbers - if your stuck out in the field with no PC - then trim down a few clicks on the THRO trim.  If it still won't arm connect FTDI and use the JAVA-Config (see below - install JAVA) to make sure the Throttle PWM is below 1100 (normal THRO range is 1095-1905) - In order to arm - the Wii  CPU is looking for THRO and is a valuable guide to trouble-shoot a CPU which won't apparently arm.   For PARIS Sirius™ AIR the internal green LED is out of phase - the phase of the LED is toggled by software are the user can have it either way by commenting IN/OUT this line in config.h        #define PROMICRO10  - the default behaviour is to comment it in - changing the phase of the LEDs does NOT change the armed status.   Always confirm the ARMED/DISARMED status in the GUI with Props OFF. Again make sure BARO is off - GPS is OFF.  Another thing for arming a servo equipped drone - Tricopter/Avatar can be coded to ARM with ROLL (as YAW will tilt props close to the ground) - Pilots choice - Code selection 


Disarming - Learn to DISARM the ESC's before touching or approaching the Copter ESC's/Motors can start suddenly and the props can cut fingers and eyes - permanent injuries!! so With THRO OFF ; Hold the YAW stick LEFt for 1 sec ; then the external Andromeda LED will go OUT and stay out (The internal green LED will be on)  Always confirm the ARMED/DISARMED status in the GUI with Props OFF.  Once you are 100% sure you understand it and have personally confirmed it in the GUI - then fit props and fly.
Gyro Calibration - Disarm the copter (see above) ; Place the Copter on a perfectly LEVEL LZ - it must be completely static - Check all Tx Trims =  neutral - Stand back - With THRO off, Hold the YAW LEFT and the Cyclic stick Back for 1 Sec ;  release - you will see the GREEN LED blinking fast for a few secs then go out - The Gyro is now calibrated for gyro drift (at this ambient temperature) - Note : The Gyro on a PARIS board now auto-calibrates in first 4 secs after Powering up - in the outside air temps where you fly.  However the Acc does not - see below.  It still pays to know how to do a gyro Cal - and if you get any strange drifting behaviour - always do a Gyro Cal and an ACC Cal(below) - you do NOT need to re-calibrate more than once a month.
Accelerometer (Acc) Calibration - - you do NOT need to re-calibrate more than once a month. The PARIS is calibrated before shipping out, at 25°C - However  if you Ops are at a different temp a temp bias can be introduced need a re-cal, so for your Ops temp set the Copter level 0.00° - Press CALIB_ACC - (after first Flying the Copter in ACRO mode - Trim out any YAW using motor tilt (3-5°) - Dont D Don't Tx trim - all Tx trims must be 0) - - Land - Switch over the HORIZON or ANGLE mode - hover STILL air (no wind)  - if the copter is drifting by more the 2° tilt the calibration is effected by temp and you need to do a field Acc Cal -> land - -  
Disarm the copter (see above) ; ensure the Copter is on a perfectly LEVEL LZ - it must be completely static - 
 Confirm the DISARMED LED is OFF - Hold Full THRO/YAW LEFT and the Cyclic stick Back for 1 Sec ;  
 release - you will see the GREEN LED blinking fast for a few secs then go out - The Acc is now calibrated for LEVEL mode (at this ambient temperature) - The ACC on a PARIS/warthox board is the Nunchuk®.  
MAG (Compass) Calibration - to do  field MAG Calibration -> Move the aircraft to an outside area 15m away from cars, cell phones or any ferrous (magnetic) material (including cars, buildings or re-i in-forced concrete etc)
Make sure you are Dis-armed - all Modes OFF - ACRO mode - move the throttle carefully to full/right yaw full ; and cyclic (Elev) full back toward you.  
PARIS AIR - make sure your max throttle >1900 yaw >1900 and Elev <1100 - there is not LED flicker - you have just 30 secs to complete the rotations ;
During this time rotate the PARIS 360° - in X , Y and Z axis - finish with the craft level on its skids (or held level in your hands) 
the process is complete when the red/blue flicker stops and you see only green LEDs on top
Accelerometer (Acc) 2° Trimming - Also called auto-LEVEL trimming - FIRST do after the GYRO & ACC calibrations and normal ACRO trimming (see above).  LAND.   
Switch over to LEVEL mode (Gear Switch).   
Take off and mentally note the way the copter wants to drift - DO NOT TRIM THE TX 
- Land - The final ACC trimming procedure (below) is this -DISARM (see above - the Green LED will go OFF) Move the THRO to the 'Learn Position - full up) - in this example the copter was moving back and right - so ; using stick-banging - move the cyclic (right stick) up once (led blinks) - then left once (led blinks) - these alterations are saved to the CPU memory.  ARM again - hover and repeat the process until the copter hovers 'level'.  Each Stick-bang = 0.1°

Question - For the 6 wires Receiver (Rx) cable what are the inputs ?  answer = Most Rx have the THROttle on Channel 1 - but futaba (DevO) have throttle on Ch3 - some radio makers call channel 5 and channel 6 by old outdated fixed wing names like Gear or flaps)

so for Devotion ( = futaba) the wires have THRO = white on Ch3 -then the same sequence as the other end

Yellow = Elevator = Ch 1
Orange= Aileron = Ch 2
White = Throttle = Ch 3
Green = Rudder = Ch 4
Blue = Gear = Ch 5
Purple = Aux 1 = Ch 6

For Taranis / JR / Spektrum - the wires have the same colour sequence at both ends of the cable Rx->PARIS

White = Throttle = Ch 1
Yellow = Elevator = Ch 2
Orange= Aileron = Ch 3
Green = Rudder = Ch 4
Blue = Aux1 = Ch 5 (Spektrum call this Ch GEAR)
Purple = Aux 2 = Ch 6  (Spektrum Call this Ch Aux1)
