Product Description

CarbonBird 18A OPTO ESC BL-Heli 14.4 active braking made for mini-MultiCopters - run at 3S or 4S  an ultra light weight 6.0 gram construction with excellent thermal properties for a 300 watt micro ESC - the MOSFETS are specifically selected to run BL-Heli 14.0 with the least amount of heat production and highest efficiency.  This is opposite to the majority of ESCs retrofitted with SimonK/BLHeli which actually run much hotter and are less efficient - We have selected very carefully the BEST mosfets to run on BHHeli -  for code which is OneShot enabled - these ESCs are OneShot ready - auto sensing.


Notes for BL-Heli 14.4
CarbonBird 18Amp opto ESC BL-Heli 14.4 ships out pre-programmed and optimised for best performance - for most motors - OneShot is included/Ready - we recommend NOT to alter our BL-Heli settings for Scarab Knife mini quads ; However please note well, for some motors or some motor/prop combos DEMAG COMPENSATION must be turned ON by the user (this includes the Carbonbird 2400kv RED demag-on-red-motors.jpg) - For example, if the motor stutters/stalls as throttle is applied immediately cut power and (if off) alter DEMAG to ON - if you simply ignore a stutter/stall and continue to advance the throttle you risk smoking both the ESC and the motor because settings are not tuned 

To use BLHeli software to alter your ESC settings

  1. Download the BL-Heli v 16.4 Win 7 program .exe HERE  approx 40mb -
  2. Select Blue 12amp Multi - 9600 Baud
  3. First connect ESC to the Linker, then 2nd plug the Linker USB to your PC and finally 3rd the LiPo power the ESC by its power plug. (last) - flashing ESC can result in "smoke" - at your own risk - this is especially true if you use a chip level boot-loader clasp over the CPU pins and the pins are not aligned to the cpu pins !  less likely with a 1-wire connector - but esc can still be smoked or firmware damaged needing a boot-loader level re-flash by you - wrongly flashed firmware can also smoke your motors !
  4. press connect - then flash the firmware first (Flash BLHeli - it can use the Simon_K boot-loader present) - this may need to be done twice in some instances
  5. Then copy the settings for this ESC CarbonBird 18a 
  6. UART - You can use a USB to UART linker for ATMEL, then download the USB VCP driver HERE for that UART ; Remove the ESC RED centre wire (lift tab and slide out) Make sure you power the ESC using a 3S LiPo to connect to BLHeli & flash, as the USB linker does not provide CPU power for the ESC. After flashing is completed - disconnect - unplug the servo lead and re-connect the red centre wire (not needed on some hardware UARTS as they have not connected their centre pin at all internally)
  7. make SURE you have the latest version of BaseFlight or CF !
  8. Now for the good part - go back and increase your "P" values ! Obviously this is done in steps of 0.2 from your previous setup - an oLED is best for this - take it up until 0.3 under any oscillations.

Features / Specifications

The main advantages of BL-Heli software are
Uses Active free wheel and active braking (PWM Damping) - 14.2 is OneShot ready for Hero•32 - this actively slows the prop/motor down on one side of your Quad, while speeding the prop on the other - without "active-braking" the prop has to slow by inertia and drag alone - this DAMPING - Light puts the brakes on - the Quad handles better - but you must also increase "P" slowly in 0.1 increments to see the full benefits.  Naturally active braking uses battery power and reduces flight time - so does having your gains too high - do yourself a favour and reduce the P

  • Output  300 watt Continuous 18A as 3s or4S, Burst 18-25A MAX 5 to 10 Secs for reasons of heat melting insulation of winding wires in your motors . (also in reality your 1500mah battery cannot supply these type of amperages 100amps haha anyway to 4 motors)
  • Speed - both 400hz and 490hz compatible - CleanFlight, naze32, PARIS v5r2 , PARIS Air v2 & MultiWii tested with mini motors to 25,000rpm (actual test here)
  • Heatsink : not required - be aware you weak link is melting the insulation on your motor wires if you hold full throttle too long
  • JST & GBC ; fitted with JST female and 2.00mm long-bullets (GBC)
  • Input Voltage  3-4 cells lithium battery 
  • BEC  Not included - this is an OPTO ESC
  • uSEC range  These esc are programmed to BL-Heli = idle ≤1100   - mid 1500 -  high throttle ≥1864 uSec ; but (we recommend to set high side to more than >1900 so that advanced stick calibrations will work  - MAG CAL and ACC CAL etc will then work too) so For YOUR Tx we actually recommend 1064/1500/1905 
  • Size:  32mm (L) * 12mm (W) * 4mm (H)
  • Weight 6g including all wires and plugs
  • push-button Program card - Does not require or use any program card - please note as all programming done via this UI using this USB device HERE for ATMEL ESC (CarbonBird Black-wires ESC)


Important beginner NOTES on ESC set up :  Read this before connecting any ESC !!

  1. DO not connect the ESC back to front - i.e. reverse polarity - You will smoke it!
  2. Do NOT apply any forces sideways to the output 2.0mm GBC female connectors - you will break them off ! - Use Inox lube - take care to push connectors in straight in using lube a non-conductive lube like INOX for all ESC push connectors. These sprays have short and long term benefits and will ensure a happy long relationship between motors and ESC's. Without lube you will incorrectly revert to brute forces - with lube the GBC slide in with no force and can be removed a year later in perfect condition too.
  3. Do NOT use pliers or steel tools to grip the ESC or connectors, nor squeeze GBC connectors - the best method is to use INOX protective lube and push together gently with human fingers - no tools please
  4. If cutting and soldering wires - make sure to solder all ESC wires with Flux Paste (Not flux core solder) - For push connectors a bad connection (a loose fitting connector)  or dry solder joint(no flux) - will cause the ESC to burn/fail and the motor to possibly burn as well.  Check all wiring with a DMM first.
  5. Does it need programming?  No - You must use the correct throttle range <1064->1864 uSEC (mid point will be 1464) - for MultiWii stick calibration of ACC and MAG you will need >1900 anyway
  6. During first throttle up power check - concentrate on the motor response - if the motor hesitates or stutters - or the prop twitches back and forth - IMMEDIATELY cut power (throttle OFF) - investigate for a broken wire in the motor - a shorted wire in the motor (mounting screw ruptured the windings) - a shorted connector or insulation cut  - or anything blocking the motor from turning (a screw from your work bench trapped inside on the magnets).
  7. To reverse the direction of rotation of a brushless motor exchange any 2 of the 3 motor wires - or reverse motor in BLHeli - linker required (not included)
  8. Use a power meter to ensure you are not overloading the ESC at WOT (full throttle for the prop) - ESC works hardest at mid throttle - so it's useless to think that if you don't fly full throttle you won't overheat the MOSFET because you are not using all the amps - completely opposite - the ESC will overheat if the kV of the motor is too high for the props used.  You must do a WOT check and make SURE at full throttle the MAX amps are 22amps or less for <10secs!!!!!

  1. 1100kv motors 8.5inch HQprops

    Posted by Paul Waghorn on 31st Jul 2016

    I got these tiny ESC's for a custom build, 4S QUADI 400 running 1100kv motors with 8.5HQprops.
    Thought they might be too tiny but they are running really well. No problems so far.

  2. There is a LOT of FIGHT in this dog!

    Posted by Breck Nolen on 9th Oct 2015

    The ole saying, "its not about the size of the dog in the fight, but the about the size of the fight in the dog".....well, these are small, but they fly BIG! I am amazed at the quality and speed I get out of these ESC's and my race motors. I went from using huge bulky heavy ESC's to these and cut weight and upped my power SIGNIFICANTLY. The active braking makes your flight so much more locked in. Getting in and out of corners, punching it and last second dipping to make a gate, these do it ALL!
