I love my Hangar 9 Aplha Trainer. The engine is so reliable. It doesn't balloon, even with the flat bottom wing. It can go inverted and what ever else you want it to do. Plus it goes together in less then an hour, and a 24 battery charge of course. It is so easy to fly wont do anything unpredictable and $300 for the plane, radio, engine, and servo's can't be beat. Here is a online review.
