You can start with a high wing trainer then go the Hanger 9 P-51 mustang pts it is a "trainer" but i would get the high wing trainer first. The mustang pts has training stuff with it and can later be taken off to be a sportish warbird. I have one for my 2nd plane. I love it and i am thinking of taking the droops of it soon. For a trainer i would recomend a Hanger 9 Alpha that is what i had and i liked it a lot.
If you take the time to learn on the trainer and even after you solo fly the trainer for a while to get good, then you could move on to the mustang pts.
The most important thing i can say is GET A INSTRUCTOR, they can save you a lot of MONEY!!

P.s if you do get the pts dont use the gear doors/air brakes they slow the plane down way to much!!
