Youll love the Aircore 40. It flies well and bounces even better. The Aircore will survive several HARD crashes and keep on flying. Ive had mine for almost a year and have crashed it hard 4 or 5 times, these crashes would have made toothpicks out of any balsa trainer but the Aircore only requires a few minutes to repair and is ready to go again. Get one for your first plane (or second if you started with a balsa model) and you cant go wrong. Any .40-.46 with a 10-6 or 11-4 or 5 prop will carry it around the sky quit well. It can do loops, rolls, hammer heads and nose dives to the dirt, all day. Now I'm ready to take out my scratch built balsa trainer and give it a try, I think it will survive now because the Aircore has let me make my mistakes.
