PWM output jitters?

I can’t figure out why my PWM outs are unstable and not responding to commands. Any idea what might cause this? The servo out has nothing assigned to it, and when I try low/med/high in the servo tab in MP it doesn’t respond. The rate is default at 50hz.

Here’s a video of what a servo does when plugged into it.

Hi @vosair,
Usually jitter is caused by noise induced due to telemetry device or others. Did u try cleaning up the wiring a little bit and move the servo cable away from any telemetry device or UBEC or others. Hope that helps.
Also request you to post an image of your wiring to get more info.
