Any short M3 screw will work. The length of the screw depends on the thickness of your motor mount plate. Just make sure the screws are not too long because otherwise you will damager the internals of the motor.
What are the best options for programming to fly with governor mode using this motor in a heli?
using a pinion of 13T and a main gear of 150T combined with this motor what would I expect for head speeds using a 3S 2200 25C LiPo ?
!!!ATTENTION!!! This motor is 3550kv!! NOT 4000kv at the first Review. I bought thinking it 4000kv and repented! characteristics: 3.550 kv shaft 3.175 mm cooling system(very good). I recommend it to anyone 3550kv motor. . . ATENCAO!!!! Este motor eh 3550kv !!!! Nao 4000kv, como no primeiro Review. Comprei pensando ser 4000kv e me arrependi! caracteristicas: 3,550kv eixo 3,175mm sistema de refrigeracao(muito bom). Recomendo para quem quer motor 3550kv.

This motor is on my Mini Titan, and preforms exelent. It much much better than the stock one as for power, as well as at battery and ESC.
Requires something like 15pcnt less mAh, BUT delivers more power.
I fly soft to hard 3d at 85pcnt flat curve throttle for 4 min, plus12 / - 12 , with a 40 A ESC and 2200 flightpower at 25C, and I use 1100 mAh of my lipo. ESC , battery and motor after the flight are cool and ready to go for another round 5 stars

The shaft of the motor goes up because unscrew the little hex screw that retain the shaft in the intake air side and destroy the cogs of the main gear of my HK450GT. Control this hex screw before install it and secure it with thread locker.

After 6 min. flying, battery gets slightly hot, ESC is cool enough, motor is slightly warm. I was done mild 3D like roll, flip, pump action and stall etc. During the flight, the head RPM is constant and there's little down of head speed. I felt the motor have enough power and speed, also ability to keep the torque and speed.
