Well I went to our field today and had better luck with the Tower Hobbies .46 engine. I was able to get couple flights in. The first time I tried to take off, I hit some cross winds and the Alpha did a nose dive into the ground. I destroyed the prop and had to glue a piece of wood on top of the fuse, where the leading edge of the wing rests against. Other than that, the plane was ok. The engine shifted a little so I had to realign it back in place. It happened right as soon as I got off the ground a few feet so the damage was minimal. I'm glad I didn't destroy it completely. That would have sucked. Also the carb barrel got some dirt around it so I had to take it out and clean it real quick. I plan on going back tomorrow evening to fly some more. It's so much fun. I just need to watch out for those cross winds. Thanks to all of you for your help. Here is a pic of what's left of the prop:
