Title. I've been trying to make a small mod to allow the CUP Merlin and Mi-8 to use the advanced flight model for use by my unit, but I've had no luck thus far. All I've been able to find after fairly extensive searching is a guide on writing a new advanced flight model, which while useful, is not exactly what I need - I'm asking here because I haven't been able to find information on how to edit a class to use the AFM anywhere. Does anyone have experience with this?
