Im kind of at a stuck point with retracting my gimbal, I cant figure out how to do two things (one or the other).
Ive got a single axis stabilized gimbal for roll control on an aerial mapping plane.
I want to change the angle of the stabilized roll servo to move the lens to 90 degrees and prevent scratching on landing.
So far I cannot figure out how to execute a command in mission planner to move the stabilized servo.
I could also use the transmitter to manually move the servo, but that's not working either.
output channel 5 is stabilizing the rolls servo effectively, but I cant move it via the transmitter even with the input channel set and the transmitter setup on a switch.
However, if I change the output of channel 5 from stabilize roll to manual, I can control it via the tx.
Am I missing something here? Is there a way to control a stabilized servo?

I've been searching for an example of a roll stabilized gimbal so can build one for my aerial mapping uav. The only example I found was the one used on Marcus UAV zephyr. Would you mind sharing your design?

About the twitching and jitter for gimbal stabilization : there is nothing you can do, this is a known restriction of the APM hardware and is probably too weak processing wise to update the gimbal position fast enough.
Lots of people have tried different ways (analog, digital servos, various ports) without solving this issue.
I guess we will have to migrate to PX4 hardware autopilot to get more processing power.
ok, Im getting closer. I changed the Mount Operation Mode in standard parameters from GPS_Point to RC_Targeting.
Now, the switch will move the gimbal to a set position, and its stabilizing. BUT, it got a very bad twitch and jitter. I have no idea how to fix this. Any assistance?
