Hi Straffo. Yes, I just recalibrated in AH and in my control panel in Windows 98.
Now, the throttle on single engine aircraft works fine.
HOWEVER, when I advance the throttle on 2 engined aircraft, one engine rpm increases while the other decreases. When I retard the throttle, the opposite happens. The engines are at even rpms when they meet at the middle of the throttle range.
4 engine planes are screwed up too. Maybe my Microsoft Sidewinder is faulty... Off to work right now, but I'll try recalibrating again later. Thanks, Straffo.
