Motor mounting screws loose

[gfm1135]

The 2 screws for the motor mounting comes loose or comes out after each run. Any suggestions? Thanks!

Really??? I will just throw a blanket reply out there. Make sure they are actually tight. Use loctite if they still come loose. But I would have to say that tha PROP or COLLET on whatever you could possibly have is WAY out of ballance causing this to happen. I have seen many times the motor screws themselves coming loose but not the mount screws.

It is the screws holding the motor to the mount.
