I just got the Avanti II and the problem is that I cannot change the heading bezel with the heading knob inflight or change altitude with the altitude knob inflight. The mousewheel doesn't work with these two FMD knobs even when the autopilot is deactivated. Other than that its a great ship to fly. I realize the computer steers the aircraft on the long legs but when on final you have to fly it manually..any tricks to this question? The manual says nothing about it. Thanks!
