Jim, Pay attention to the advice on leaving the PTS P-51 alone for now. I have flown the P-51PTS and it would not last long if you do not have help. You want a slow and stable plane like the Kadet Senior or the world models version of the senior. Do not underpower it, use a good 46 ballbearing engine. A simulator will help but you really need an instructor to help even if you have to drive a ways to get it. The Nexstar would be a second choice if you had help setting it up as it really isn't a fuel and fly from what I have personally seen.
