I have it on several of my planes and skydivers - almost all the time its the radio to close to the receivers -dont ask me why - all the old timers swear its the servos ,so I just smile and have the plane flown anyway and all is good astrhe ol timers kibitz on when its gonna crash - been going on over 3 yeears so far and all planes flying - never a problen when radio over 3 ft from plane

Me , I would not worry about it and just keep radio a few ft away from plane when trimming and go fly and injoy
