Sub-Micro Hitec servo PC board (HS-56HB rated at 4.8-6v), with 4.8v input to 3 pole servo motor from a slightly bigger servo and pot-meter from an X-Mods RC vehicle. Soldered all and works to some degree with a TX and RX but very very sensitive and jitters like mad! When the TX is turned off and the RX is on the servo stops jittering but rests to one extreme. I tried the pot from the micro servo and a bit less sensitive but still jitters off the charts! I also tried to swap the two power poles on the motor oposite but the servo then just moved to one extreme. I also tried a few different caps and resistors I had from 540 size motor rebuilding but either no help or same as no power. I'm stumped. Thanks for any help!!

When a signal comes from the TX to shift the position of the servo it moves to the precalibrated point. That point needs some space to prevent it from jittering. What's happening is the servo is overshooting the "low" limit and hitting the "high" limit which is causing it to "jitter" between the two points. This usually happens because of inertia in the servo motor and the gearing being too high.
Increase the width of the stop point or gear your servo motor a little lower.
