i have a 300x with a 7200 beast. I have rebuilt the 300x all the the way with lynx upgrades. (complete frame, gears, tail, rotors, etc....). Now at high RPM or at take off I have one servo that starts jumping. On the Beach with no rotors on there is no vibration. When it reaches full RPM the servo starts jumping and then pulls down. Does this mean I need to replace the 7200? If so what should I replace it with.
