I would have to do this for all 6 axis as the speed gradient is for all of them. And as I wrote I need the gradients as they are. That what you propose is not very practical also as I would have to strongly reduce the gradient between both deadzones in order to not have abrupt jumps and this would make TrackIR quite useless.

I think the solution I propose is quite easy to implement and still be fidel to reality as far as possible. Up to now because of the TrackIR thing aiming with 109 is unrealistically far(!) too difficult compared to centre sights.
