Hi! I am a participant of a student team which designing and producing Unmanned Aircraft Systems and going in competitions like UAS Challange of Institution of Mechanical Engineers.We are trying to transfer our real aircraft to real flight but while we are doing it there are several problems.First of them is Real Flight is not able to understand to difference between the parts of aircraft even if we do naming of parts (like ~CS_LMW ets.) and drawing parts as a whole.Second problem is we have to take an another aircraft as starting point and we could not find any inverted v tail aircraft even if we looked all of the rfx files on KeMax website.What we can do to import an inverted v tail aircraft to RealFlight? Do you have any advice or idea for us? Thanks for advance...
