Neu shaft keeps slipping
 

Hey guys!!! Its been a few yrs and now back in the game!!!
Im now going to finish the conversion which I didnt get to.
Its a revo 3.3 running 6s with Neu series motors. Question is how can i lock the shaft to the pinion?? It keeps slipping!!!

Did you grind a flat spot on the shaft?

no i havnt... whats the best way? Dremel with the shaft held in place?

yep!

Sweet as!! thanks guys!!

put the motor in a ziplock bag and poke the shaft out. You'll keep all the filings from flying into the motor.
(not my idea, just passing knowledge around, I've read it before on here)

Also wondered why didnt they come with the shafts grinded just like other motors on the market?

Neu motors are originally designed for air use and propellers/fans are subject to much less torque, so they don't necessarily need a flat spot on the shaft, but it still doesn't hurt and they should include a flat spot anyway IMO.

I see.. Thanks :)
