RE: Glitch Busting Help
My experience with the 56xx series of Hitec digital servos is they are prone to glitches. They have never caused a crash for me but will sometimes move off center then return. The first two I had I returned to Hitec and they were replaced. The new one did the same thing. I then put them in a new airplane with new electrics and got the same funnies. I no longer use them in critical applications.
The electronics in the servos will also reboot if the voltage gets too low. Using 6 volts will help this problem.
