Turnigy TG9e jittering

I think jitter is the correct term. I bought a few of these to use with the pan/tilt mount. In one direction both servo's are fine, but in the other, then end point doesn't hold, and the servo jitters back and forth. These are certainly cheap and cheerful, so it's not the end of the world. I was just looking for likely causes and if they are fixable, or whether it's a case of binning them and getting another pair.

Hopefully this short video demonstates what I'm on about -

	It could be a couple of things Try setting the end point on the tx a fraction lower (it could be trying to travel past the actual end-point) Possible (but less likely) is a dirty track on the wiper at that end. some electrolube may fix that
	I don't care what it says on the profile - I'm so NOT GB!

	A little late, but this doesn't seem like an uncommon problem, i bought 10 TG9e and at least 2 of them are showing this problem after running for a few minutes. I also encountered this problem in other cheap servos, but only after running them for a few hours, in those cases it seemed the potentiometer was worn out, not sure if the pot is bad in TG9e or if the controller has timing issues.
