If you are really thinking about going into warbirds, than keep the p51, but don't let the fact that you have it influence you. after you get off your trainer and go through a transition trainer, think about wat you want to do. fly easy with a trainer or something like a declathon, or maybe extreme speed is the way you want to go. look into pattern planes. If you are still pointing in the direction of warbirds (once again don't let the fact that you have it influence you) than the p51 will be a great plane that you will enjoy for years to come. If you want to go aerobatic or 3D, than something like an edge 540 or a cap 232 or an extra 300 are in order. If you use the p51 just because you have it, there is a good chance that you will not be satisfied after you get to know the plane. i understand your circumstances and all, that mistake is not at all common. we get that here all the time at rcu. you are not alone. Flying rc is a lot. Even a trainer is a handfull when you first start out. It is just in your own interrest that we reccomend that you not use that as a first plane. A lot of people get their dreamplane as their first plane, go out and try to fly it, and shy away from the hobby when it was too hard and their plane didn't make it back.
