Is that KO a digital?
My dad had problems with glitching with a Hitec 5925 Digi Servo when he was using the LRP 7.1....It glitched with everything else too but it glitched the worse with a LRP 7.1.....It was probably his radio system though....Are you using a Hitec transmitter? I found it kinda funny that a Hitec digital glitched with a Hitec radio
Maybe Hitec radios don't produce enough of a signal to overcome the digital servo? Or could it be synthesized radios don't produce enough of a signal? Are you using a crystaled radio system or synthesized?
