i'm working on a piper saratoga in fsds. when i build the aircraft mdl and base it one of the fs2002 default planes like the cessna 182rg or the mooney bravo and go test it out it promptly sinks into the ground and crashes. if i slew it upwards and then fly it, it is uncontrolable.if i build the aircraft mdl based on a beechcraft bonanza i have in my hanger it's perfect. or if i build the mdl on another aircraft i've downloaded it turns out perfect...i just can't seem to build the mdl file based on any of the default aircraft. any idea what's going on.your help most appreciated

The problem you are discribing is based on some wrong info. You have to set the right gear height in the air file to match your planes. Also you need to set your center of gravity right. I had these same problems with my Saab until I corrected the gear height data in the air file. Also I had to change the dimensions of the aircraft, because a Saab 2000 is slightly bigger than a King Air.Hopes this helps.Udo.:-wave
