The LT-40 is a good choice and a solid plane.I had one with an Enya 45cx engine and that was fine. The only problem I had with it was that when trying to land it would float forever. The darn thing just did not want to give up flying.

I also had the smaller one they make. I think that was a 20 size. I built both of these planes from kits and they are about as good as there is. Every piece fit like it was supposed to and the builds were a breeze. The instructions are second to none.
