When i produce the airplane it appears in FS2004 in the aircraft menu as UNSPECIFIED even if a name it Learjet_45 also when you view it from the spot view the spot distance start at 26 feet so it is impossible to see the airplane. Any suggestions on how to fix this??

i think its all to do with the aircraft.cfgtry using the default learjet 45 aircraft.cfg and edit it

Yes i am using the default Lear45, and never before this happened to me, it should not be neccesary to edit the aircraft.cfg to fix the problem.Jorge

maybe you coudl paste the [fltsim.0] lines here :)
