Ok - I might be an idiot.. The instructions probably say I need to calibrate the pots on my new radio, but I never did. I just started using it.
Well today I was trying to check the centering on a FrSky HV5611 servo before I suggested them for a high speed application.
The servo was not centering well. Hmm, also getting some odd jittering. Started trying to figure out what was causing the jittering. At first it appeared to be having the transmitter way to close, but I was not sold on that, and checked the output screen on the transmitter and I could see the transmitter was showing noise coming from the hall sensor. That's not good. I thought maybe I should have bought the X18S with the fancier gimbals when @Jarron suggested I calibrate the pots. In the back of my head I'm thinking that is not going to do any good, but I'll give it a try. As soon as I was done the model I had turned on went silent (servos had been chattering) and the servo test now showed PERFECT centering. Woohoo!
So thought I'd share this with you all. Don't be a dummy like me. Go calibrate! Factory calibrations does not appear to be perfect.
Also on the plus side, I highly recommend the FrSky HV5611 servos as an alternate for the KST X08H. The Frsky does more thanks to telemetry feedback and costs less, and centering appears to be just as great.
Crude centering test, a length of carbon fiber attached to the servo arm. Many $40 servos fail this simple test.
Hope this helps some folks!
