I read this :
https://librepilot.atlassian.net/wiki/display/LPDOC/Camera+Stabilisation+Configuration

I've two problem
1) When i started revolution (not connected to GCS) the gimbal moves in crazy way , after one-two minutes return normal. see the final part of this video:

2) i have analogic servo and setup ch5 (pitch) as pic in attachments, but on the pitch the rotation of the cam is not linear.. i made this setup because i want 30 degree of rotation upward and 110 degree of rotation downward.
I' have this rotation with this setup, but not linear, so the camera is not remaning parallel to the ground.
maybe I should set the neutral in the middle between min and max, and limit the angular aperture with a set-up channel 5 on the radio transmitter?

When you power the quad you should wait for Gyro initialization (do not move the frame).
At video end you are moving the quad while the board wait for a steady board to do the gyro init.

The "linear" response depends  how you mounted the servo/horn/angle, so mechanical issue and anyway difficult to maintain linear response over a wide angle range.
There is no curve response allowed to compensate the not-linear response.
