CarbonBird™ 3515 ss - 1111kv - 850w FPV fixed wing motor - 11x5 HQprop INCLUDED - FPV motor has been developed by MWC to fly the bigger 1500~2000mm FPV planes such as FX-79 Zeta here or FX-61 Zeta here, wings or Twins and suits 12~10" props running 3s-4s. Features NMB Japan bearings - tightly packed with copper wire -  the motor can be run on [email protected]" for stealth or [email protected]" for a higher cruise speed ; the design of this motor's->propshaft assembly is superior for twins - included are left and right hand threaded shafts with self tightening nuts for Twins FPV which will use counter-rotating props - completely removes the need for a prop adapter if its setup as a twin-puller rather than a push motor in a twin)  In a Pusher wing the Std shaft is used .   The 3515 stator features high torque and good cooling - and is optimised for a 40mm spinner

Includes

• 1 x Carbonbird™ 1111kv red Motor ; 100mm wires ; 3.5mm GBC (includes Female GBC connects also)
• Includes 11x5 HQ prop  (1) (see here)
• 1 x M5 Nyloc nut ; 1 x Steel flanged nut for each threaded shaft
• 4 x M5 Washers red
• 2 x twin-tractor shafts 5.0mm with M5 threaded section - one shaft left hand threads - one shaft right hand threads (these are for a twin setup with counter-rotating tractor props - on the front of the wing such as Twin Dream, XUAV-Clouds)
• 1 x pusher Prop Adapter 6mm Ø ; red M6 spinner (can be used for Pusher props like Zephyr Z2, FX61, FX79, SkyHunter, Sky Walker) 
• 1 x spare motor shaft 5mm
• 1 x set of 3 female GBC 3.5mm
• 1 x spare "C" clip
• 1 x "X" mount (with 4 M3 bevel screws)

Motor M3 bolts HERE - be sure your mount bolts are NOT too long - very important, as bolts must only enter motor 3~4mm .  This motor is supplied fitted with plain/keyed shaft and a 6mm Ø Prop adapter for fixed props; tip -> place 1 drop of Loctite on motor shaft then slide PA on ; mount prop first, washers last; tighten spinner symmetrically ; don't over-tighten from one side; use a socket not a wrench - we recommend 3s use an 11" or 12" prop (or for 4s use a 10" prop) - for twins with counter rotating tractor motors, just tap out the shaft and insert one of the threaded shafts included.

Excluded - Folders - for belly landing wings and thermal gliding, glide descents,  we also recommend a folding prop set up - so consider fitting an Optional (excluded)  AeroNaut™ Mittelstuck + AeroNaut™ 40mm spinner  + AeroNaut™ 12x6 folding props (3s) ; or AeroNaut™ 10x7 triple blade folding prop for 4s

Note about other "no brand" cheap folding props ; AeroNauts are not cheap, sure ; but we have tried cheap clone folding props from HKing and they are frankly rubbish ; you will find the out-of-centre vibrations from such cheap folders mechanisms OTT and you GoPro will gello ; and worse your AIR3 IMU will spike causing iNAv to malfunction.  It's very important to ensure you have a silky smooth motor + prop.  It's vital for FPV.

Excludes/Requires

Excludes Spinner for Folding Prop

Excludes MittelStuck Centerpiece HERE

For 3s Ops  11~12" fixed pitch prop for 3s Ops or   Folding Prop 12" HERE  - Folding props are Highly desirable for FPV because they enable long range high speed gliding and thermal climbing when the prop is folded back.  

For 4s Ops use these Prop 10" fixed props HERE or folding 10" prop is here - we also have the super cool 3 blade folding MittelStuck centrepiece HERE and matching 3 blade 40mm spinner for 4s Ops
