How to set throttle as one axis instead of two?

[kingpinda]

Don't know where the double axis is coming from.. not familair with the x42 but your throttle is not a split throttle? you can't unlock it so you have 2 throttles? are you sure you are not triggering some other axis? a wheel or rudder or whatnot?

Anyway... for the range on your axis try tuning it in control page -> axes tab -> then click on the axes you have assigned. check the bars that appear in the bottom of the screen. fiddle with them so the input -> output bars behave the same. Its a minigame this is. almost every axes needs to be tuned like this in my experience. doesnt'work straight out of the box.

edit: check your saitek software btw. has your throttle set up by using bands? or slider or something like that?
