RE: 480 Park motor problems
I slightly bent the shaft on my Park 480 on a pretty bad crash. I transfered the motor to another plane but the bent shaft was enough to vibrate the plane, so I ordered a replacement shaft for it.
I replaced the shaft, and the motor works fine. However, I noticed that if I try to turn the prop clockwise, there is a lot of grinding noises. No grinding when it turns counter-clockwise.
Any suggestions as to what is causing that grinding noise?
