Serious servo jitter
The radio was purchased here on RCU, it was NIB but the guy who had it wanted to keep the receiver and servos. He did substitute a off brand receiver (junk) which was immdeiately discarded. Being as I needed a receiver I ordered a new Hitec Supreme and the appoppriate crystal. It seems a little odd that the 517's work perfectly and the 527's jump around. Other than sending the radio and receiver in for a check up/tune up, I've tried pretty much everything I can think of.
