My 3-axis Alexmos is set up and seams to work by its self on all axis's... but when I use the RC Radio to control the tilt, the gimbal rolls a little as well - I also noticed when I yaw it happens too (the roll does not stay level)?
Follow mode is off, I have no idea what might be causing this.
I have the same problem. I have follow yaw set on so the camera follows the yaw. However whenever i yaw the roll axis tilts by up to 5 deg. I have disabled the RC roll to no effect in fact i think iv tried almost everything to remove the problem without effect.
You should also in the rc tab below where the roll says -45 degress and 45 degrees, set it both to 0. I have only a little bit roll when i use a analog joystick for the pitch, when i tilt it down the roll goes 1 or 2 degrees of. But not on yaw.
