Just received my Model Airplane Mag today and David Scott, 1st USFlight School is endorsing products for Great planes for their simulator and also for Hangar 9s PTS P51. Mike does that deem him at least somewhat professional in your eyes. I would think that these companies would have at least checked him out before allowing an endorsement from him. I know pro atheletes are not always what they seem on the surface but at least you have to admit he is not some fly by night huckster.
