I haven't seen all the planes that come on the G3 simulator yet, but I would doubt that the P-51 PTS (trainer P-51) would be on there. Realflight is a product of Great Planes and they usually only put Hobbico/Great Planes planes in that simulator. The P-51 PTS is from Hanger 9. I could be wrong, but I wouldn't hold my breath.
