No real difference that i could spot.
As others have said though, if i add weight to the servo, it moves a little smoother, but i can still feel the individual steps though.
Also the servo's are incredibly noisy in "neutral". I guess the Rx is switching back and forth between two "steps". Very seldom do i manage to put any of the sticks so that the servo does not make any noise.
I added my DIY module to an old radio. The servos jittered at neutral and the motion was choppy. I scoped the +9.6vdc supply and the PPM signal line. Both had approx. 300mv of noise riding on supply and signal. Going to power reduction mode lowered the noise to 100mv and the system seemed to work better. The problem was a defective 9.6vdc nicad pack. Wired in a new pack...problem went away and servos are quiet and smooth. Scoped the same lines and they are completely clean and flat. Apparently my problem was loading on a bad power supply. Going to reduced power obviously lowered the load and the system appeared to work better. Scope your power supply to see if there is any noise at all on it.
