Hello !How can i import a mdl-file into the programm FS Design Studio? I can only open .fsc files (Project Files from this Program...)

You can't

F***, i bought this Programm at e-bay :-( :-#

You wouldn't be able to do it with GMAX either.Suggestion: Open the program and try and create an aircraft yourself.

Good idea, thank you.By the way that is the thing i want to do. But my suggestion was to learn from a model which is finished.

there are many source files available at http://www.freeflightdesign.comfor you to learn from :)

You might try some of the *.fsc files found at http://www.freeflightdesign.com/ .W. Sieffert
