RE: Nexstar Trainer engine size
Regardless of the amount of hype that the P-51 PTS gets, it's still not a trainer for everybody. It needs to be kept at a higher speed on landing and has a few other characteristics that move it into the "advanced trainer" category. I'm not trying to take away anything from Hanger 9 because they did a great job of making a trainer out of a P-51, but there are going to be a lot of students that this plane will just be too much for to learn on from the get go.
