Gains are already up, sinking removed, I am thinking about reducing them slightly as it's eating battery like there is no tomorrow. Currently at:
Basic: 120% 120% 120% 120%
Attitude: 200% 200% (unchanged).
Probably going to drop all the basic 10%.
I am also going to totally undo the thumbscrews, take them all to 8 an then back them off incrementally, job for tomorrow tbh.
The roll horizon thing is not from calibrating on the ground, I was launching from a dead level surface in the garden astride 2 bricks for gimbal clearance. What happens is the camera rolls and then very slowly returns to level in something in the order of 10-15 seconds, this is intermittent following hard right on right stick. I was trying to do this close enough to see if the cable on the rear of the camera was fouling, but no luck this afternoon.
