The calibration with FSUIPC is done (this was one of the primary reasons for why I paid for FSUIPC in the first place). ;D

I have it set so that when my joystick throttle lever is full back, the throttle is set at 0% (the stop position). This is/was reflected in the VC with the throttles showing 0%, but it still rolled forward. Parking brake was set and using the joystick button 1 (set for the brakes) it just would not stop rolling away on me.

I plan to try the 707 again, but I'm just trying out a few others at the moment, to see how they perform in Windows 8.
