Bought a Neu from a member here that had a loose shaft. So I sent it back to Neu. Got it back 5 days after I sent it off, and they replaced the shaft, and put the screw retained rear endbell on...all free of charge! Good service!!!
Now take a look at the motor shaft, it is very long! 30mm to be exact!! Must be for a heli, or something like that... I am not complaining, as it was free!
