Would radio interference on a non pcm radio if someone turned on the same channel cause servos to lock up or become jittery. Would the aircraft fly in a squirrly path or lock and go down rather quickly. I was flying a stearman and she went into a left bank I tried opp ail but got nothing tried full up elev got nothing after the crash all controls worked perfectly. It was a very humid morning could I have stalled out after a series of loops and rolls. It was a 10 year old jr 5 channel radio.
