RE: Engine mounting position.
What Crasharama said it dead on good advice. Just because it says "P-51" doesn't mean that it's the same plane that you are trying to fly. That's kind of like saying a Ford Tauras is the same thing as a Ferrari because they are both a "car". The Hanger 9 P-51 PTS that is listed in my list has been designed to be easier to fly than any of the other "real" P-51 warbirds out there. Even though the PTS has been calmed down a bit, it's still not a trainer for everybody. It's more like an advanced trainer or even a second plane for some people that are learning to fly. But I can assure you that even using the P-51 PTS you still wouldn't be able to learn to fly by yourself.
