At a certain engine RPM my radio gear goes nuts ? Troubleshoot..
I only fly a couple times every summer so I took my old Avistar out, inspected all the controls and went flying..
My radio is a basic Futaba 4-channel FM bought in 2000 (Skysport4 I think ?) and at certain RPMs the airplane kind of dances, and sometimes the ailerons turn 200% right and elevator 200% up during a split second. I think one of my servos or the receiver reacts to a certain vibration frequency. Anyone experienced something like this ?
