Camera Gimbal Stabilization on Pixhawk

I’m trying to set up my camera gimbal to stabilize while in flight(on a Fixed Wing), but I can’t seem to find any options on how to do this. I’ve seen that there’s a stabilize gimbal option when planning a mission, but not really anything else. So, can I only stabilize the gimbal when I’m flying? Doesn’t seem much of a good idea for testing purposes. If I can’t get it to work on the ground, no way will I get it to work in the air.

You’re in the wrong place. You to talk with firmware or hardware folks.
