I believe a sound very close to the real thig could be replicated, but it woud take some experimentation. This would all have to do with air intake and outlet. Unfortunately, I don't have the time right now to experiment. Good luck to you if you try. My TF 1/6th Scale P-51D is powered by an OS 1.08 and flies beautifully. She is in "Glamouous Glenn III" scheme. That 1.08 sounds great while swinging a 16X8 propeller. I will eventually try a 4 blade to see what happens. Good luck.
