Zxknight,
I recommend the Avistar 40 trainer. Semisemetrical wing allows for mild aerobatics. I modified my son's Avistar by removing the factory ailerons and adding 2" stock ailerons and flaps. He can hang his Avistar in mid air and do all kinds of aerobatics with it. He may be getting a 1/5th scale Sukhoi or Cap 232 for Christmas. However, if you must have a Mustang, I recommend the Great Planes P-51. I have one with a Super Tigre .75 2 stroke and it flies great. No bad habbits either. Good Luck.
