Thanks Jeff.

I have fixed the 1940 I got from you. I need to let the jb weld dry, and give it a test run. Main problem was that one of the magnet segments craked in half and seperated from the rotor. 3 strands of the windings were knocked loose and were interfering with the rotor, but were not cut through. I have moved them back into place, and re-epoxied the winding (not done very well by lehner).

Now the rear endbell, which appears to be held on by a crimped portion of the end of the can. Well it was not parallel to the front endbell, so the rear bearing was binding, bad enough to lock the rotor. And ruin the rear bearing.

Now I will test the motor with 2s lipo tomorrow, being around 1600 kv it will not spin fast, but should be enough to test it for operation and not work the rear bearing too much.

Now, may main question is: How difficult is it to turn the shaft on a lehner motor? I can turn this one by hand, but it does not spin as freely as a feigao motor. I have some novak and aveox motors and they feel more "notchy".
