In my pro4, after i put electronics in,new servo 737,used Gt7,new synthesized airtonics reciev, at idle-no interference,give it power and just a very little frt wheels jiggle off and on,but just enough to notice it while looking at car. A fellow racer at my local track may think its the capacitor on the Gt7,said that if it got hurt in any way previously before, that the insides may be causing the glitch. I have done all the checks that i knew of but has anyone heard of the bad capacitor story on the GT7?? Thanks..Others at the track have their electronic in their pro4 the same way as me,but not necessay the same brand stuff.
