I am Getting a small jitter on the tilt axis using the Freefly servos, Radian Gyris and a Canon 7D with 11-16 Tokina Lens. The jitter is visable when i use a very small input on the stick to achieve a very slow movement, and also when the radian is correcting.. I have issolated it to the Tilt Axis, and can see it just by looking at the lens when it is moving. Has anyone else come across this???
