Tekin Gen4 Spec-R Sensored Brushless Motor (10.5T)
The main thing I do not like is the motor does not come pre-shimmed. The shaft has a lot of slop in it and it comes with a bag of 5 teflon shims. I took the motor apart straight out of the box and threw 4/5 shims right on the end of the shaft but it could have taken all 5. I will take it apart again to set it up correctly but I really wish they installed the shims from factory to get it close to a perfect setup.

I have run a G3 for a while now. I wanted try the G4 it see how much different it would be. The G4 is faster, with more torque. I’m really happy with the motor!
