Roll can be more aggressive.
Set extra deadband for rudder to help prevent accidental input.
As to deadband, in AH, esc, options, controls, map controllers.
Pick an axis, click advanced.
If you wiggle the stick and see the input line move on the "scaled" side, add just a touch of deadband and test again.
A Dead Band is an area around the center of your stick which has no input. It is essentially "dead". This is useful if your stick tries to "spike" even when you are not touching it. To see if you need to increase your dead-bands, look at the blue window on the right side of the scaling window. The lines under “Raw” and “Scaled” should be in the center and not moving. If they are moving when you are not touching your controller, you need to raise the dead band slider until they stop. The farther down you can set this without the lines moving, the better.
If you pick up the base of the joystick and "twirl" it so the stick goes around. You should see movement in the "raw" side of the graph, but not on the "Scaled" side. If you do, increase deadband a bit for that axis, and check the other axis also.
Don't need to worry about deadband with throttle normally.
