I think I've got interference from a Brisson 3.2 i,ve been running. I just crashed a second plane with this motor due to the futaba pcm reciever going into failsafe or hold. At first i thought it was a power or reciever problem but that was all replaced.

How can I determine if indeed I do have interference from the moter and correct it? I have looked for loose metal to metal contact and found none.
