Default RE: At a certain engine RPM my radio gear goes nuts ? Troubleshoot..

You might also try substituting another receiver, borrow one if necessary just for the test. A cold solder joint or cracked circuit board in the RX could present these symptoms. I'm assuming you have your receiver wrapped in foam rubber or otherwise isolated from the airframe.

Also, it sorta sounds like your prop is out of balance, the number one contributor to excessive airframe vibration. But that's only the proximate cause; you have another issue somewhere--could be metal-to-metal friction, could be corroded contacts, could be intermittent connection of another kind.
