the towerhobbies 46 is very powerful.[>:] But, its so hard to break in...The cylinder didn't wanna turn, we kept trying forever to turn it over with electric starter and for the first time, my starter got hot. It eventually went and runs great, but this engine isn't for beginners.

I'd really suggest the Alpha Trainer. I've taught 3 people to fly with this plane, and it is so stable and the engine is very, very good. So easy to start and its preadjsuted. Get the Alpha!!
