these things almost always get sorted in short order.....there are some good tips on binding in the FAQ but just in case....unbind whatever is set on the Z axis, then bind the Z axis to your throttle, run it up and down to see it's working, then save before you exit. I think by default the X is set to ailerons, Y to elevators, Rz to rudder, and the Z to throttle. Beam in if you fix your issue....good luck
