For the money you have you will love the Super Cub. It's easy to fly for a beginner. Parts are very easy to find. Parts are reasonably priced. If your not sure if he will stick with the hobby, you don't want to spend allot of cash. Most newbies think they want a small plane, because it would be easier to fly. SMALLER IS NOT EASIER. Bigger planes will take the wind better and give you more opportunities to get out and fly.

Good Luck
