OK got it. Had to take the aux from my ch14 to another as it only handles 0 to 100 % switching.
I have the default gain settings at the moment. By varying the end points on my gyro channel I can reduce the gain from 82%t to 3% (as per my PC display when I move the gyro channel on my TX) - this is obviously the % gain within the default setting on the gyro - right? Should I reduce the end points on my TX to reduce to 82%?
