Change short nPlane to long nPlane and recompile. Anyway, there is open source flight sim aiming to be massive multi player developed, cant remember its name though "Red Shift" or "Blue Shift" or something.
late B24 and late b17 are useless. Both slower than early varaiants and + only 1 nose MG. We need clear these slots for Barracuda or SM.79 also please delete Zero 5a, only difference is caliber of 1 MG. Ki-45 is the nice replace!
