Update from Dave Perry:

This patch does a number of clean-ups as well as adding a very realistic
flap switch and rudder trim.
1.  completed the rest of the "hot spots" including prop control,
throttle, mixture, flap switch, rudder trim, and fuel selector.
2.  Added a local-to-pa24-250 controls.nas to allow checking for
electrical power before allowing the gear switch and the flap switch to
do anything.  This also allows for realistic flap performance (not just
3 positions).
3. Added key binding for "[" and "]" that use #2 to make realistic flap
travel.
4.  Made the AC "sit on all 3 wheels" on the ground.
5.  Fixed an error in the check for electrical power for the nav and adf
radios.
6. Fixed some ac3d artifacts (duplicate polys, improper vertex orders,
wrong normals, etc. to improve the appearance.
7. Collected object into groups to make it easier to get the alpha order
right (you can no longer see the radio stack through the wing, etc.)
