localised radio interference
Whilst flying my twin jet and alfa f86 recently at the club field, I have suffered several massive glitches whilst flying. ie sudden dive, roll etc, and then normal flight, Ive noticed that the glitches happen in certain spots and certain heights( which vary from day to day). One recent large glitch nearly caused me to go nose in from a perfect level flight. I'm pretty much happy that my set up's are ok in that i use capacitors on the motors, and i get the correct reception, with the aerial down etc.
Is it possible that i'm getting some sort of radio/microwave interference as the glitches seem localized, how would i determine what is causing this problem?
I'm using a sanwa rd 6000, and gws mini receiver on channel 73.
