I have the Esky head lock gyro on a Belt CP.

I have all channels connected as they should be, with the gyro on channel 4 and the gyro extra wire on channel 5. I'm using the stock Esky EK-0420a RX. Well, the gyro is glitching out. It won't return tail to center, nor respond normally. When I move stick left, the tail moves the correct direction, and then sticks there. When I move the stick back, it moves the other way, but sort of sticks, and glitches out, twitching all over the place. I screwed with the gain and this didn't help. My linkages are not binding at all. It's just acting out of control.

Ideas?
