For those how are interested, Abacus have issued a newer version of the Flight Dynamics Editor. This program is freeware, and can be downloaded [link:http://www.flightsimdownloads.com/premier/fde/|from here].
FDE now supports FS98, FS2000, FS2002, CFS1 and 2.
For newbies to FS2K2 how wish to make the MD83, Dash 8 and PA28 flyable then step one is to edit the air file for these aircraft, by changing the 2 to a 0 (zero).
Hope the information is helpful to you.
Happy Simming :-wave
