a p51 is going to be really hard to learn to fly on. it is heavy, really fast but sluggish, has a very high landing speed, is not very stable, will not self-correct or any of the things you would want as a trainer, glow or electric. you should start out with a pt-40 or something. use the p51 as a third plane. that wouldn't make a good second plane either by the way. get something simple. the best thing would have been to ask a bunch of people what they would reccomend for a trainer. even the pros will tell you that was a really bad choice
