Default New Axi F3A motor: 8112/10

Bondaero just added the new (soon?) Axi F3A 8112/10 motor.
Similar in size and constructio as a Q80.
First time I heard of it was by Donatas Pauzuolis in the new Mryia biplane.

AXI 8112/10 F3a

The new AXi 8112/10 from Model Motors is a 215kv outrunner designed primarily for F3A aerobatic models with a read-to-fly weight of approximately 4.8kg. This motor has been used very successfully by Mr Pauzuolis with 10s Li-Po batteries on 2112 and 2210 propellers amongst others. This combination provides huge torque and efficient power output.

AXi 8112 motors are designed for front mounting. The threaded shaft is 8mm hardened steel approximately 60mm length with an M2 hole in the end for spinner mounting. A prop adaptor is included with two spacers and two nuts along with 5 mounting screws.

The AXi 8112/10 arrives with pre-installed probes for Jeti MT125 temperature sensors and MRPM-AC RPM sensors.

Weight 530g


$470 based on today's currency exchange GPB to USD

EspritModel (Florida, AXI dealer I believe) say they should be carrying it as well.

Hopefully Mike at F3AUnlimited will offer it too.

Any real world experience from this motor? What it the benefit of having 38 poles compared to 28 poles (Q80)?

Is anyone running this motor with success?

I am losing sync with a ZTW Gecko and YEP ESC's Tried various timing and pwm settings with a 21 x 12 prop

With no prop it will stutter andvibrate at high throttle

very smooth on start up, really want to avoid swapping this out.

It's a 42 pole motor, probably losing commutation synchronization as others have had with high pole count motors. You might try a jeti mezon esc which seem to do better with high pole count motors.

Max motor shaft-rpm = max_e-rpm / (magnetpoles/2).
Controller max e-rpm = max. 2-pole rpm (depends on ESC processor computation speed)

Max. shaft rpm for several makes/types controllers, for given number of magnetpoles
bavaria-direct.co.za (user Skylar on RCG)
→ More info
(below the colourful winding diagram table
→ ESC max. rpm limits
