The problem is that if i move either the ailerons or elevator i get a single glitch on all the other flight controls not a continuous glitch just a hit and it doesn't happen every time you move a flight control but just enough to cause concern, Ive removed all but one of the mettle gear servos "rudder" now and replaced them with 60 once plastic BB servos and everything works great now . is there any reason I'm not able to use more than one mettle gear servo at a time.
You may have a bad servo, try isolating it by adding them one at a time. start with two metal gear servo, if its fine, then add the third one, and so forth until it starts glitching.
