This plane should not be your first plane!!!!!!! It's not a trainer.
Since when is the P-51 PTS not a trainer? It was my first plane. We have had at least 3 in my club that new members have learned on and are still doing very well.
The only thing I would suggest is, don't use the speed brakes on the landing gear. If they are not set straight, they have a tendency to throw the trim off.
