One sugestion. Before you put your gear in the P-51 you should look at getting a GWS Slow Stick. It is a much better plane to begin on. And for $35.00 if you crash it you not out much, plus it is much more forgiving. Start out with the Slow Stick and once you have it mastered just move your gear to the P-51. It should work in either plane depending on which batteries you get. You may also want to take a look at the parkflyer forum on Ezone. Many P-51 threads on there.
