8231 Servo oscillates around neutral
Danny,
I have 5 8231 servos out of 9 that oscillate around neutral when when hooked up to a control surface, especially a pull-pull hook up.
What is wrong? I am using a 4.8 volt pack. Is the servo rated for 6 volts? It seems to be worse with a 6 volt pack.
Please advise,
Travis

RE: 8231 Servo oscillates around neutral
They work fine on 6V, out of the JR line only a couple mini servos and retract servos are limited to 4.8V.
I would check for any slop in the control system, arm fit on the servo, and gears for any excessive play. Also I would recommend checking all your servo connections (unplug them, re-install a couple times to be sure the pins are clean and making good contact). Also check your current draw with an amp meter to be certain the current draw is not excessive. Also be sure that your servos are not mounted too rigidly (servo screws too tight, mounting rails tight against the servo, etc). If the oscillation stops by touching the surface with your finger, it is likely a slop, set up, or electrical issue. If it does stop, it won't happen in the air due to flight loads, but I would recommend giving everything a good checkover.
