I have a Great Planes Giant Supersportster which has Hi-Tec 645mg servos on all surfaces and a standard Futaba servo on the throttle. It is powered with a Life battery. The reciever is a Hi-Tec Opti 7. The throttle servo keeps burning out. I kept thinking it was just the servo. I just burned out the third servo. It goes out after 3-4 flights. It locks up and you can't move it. Could the reciever be allowing to much voltage to the thottle servo?
Thanks,
