I had no intention of putting a 2-stroke on a cub, that would be blasphemous. I think that 2-strokes should be illegal for any scale aircraft, it defeats the point of having one modeled after a real aircraft, I just wanted to know about the possibility of inverted mounting for a 4-stroke. We have a full sized cub, and I basically want to make it as close to that as possible. I know it isn't the best scale model, but it is a start. It would have been cool to get one of the 1/3 scale *really scale* cubs, but the kit that I found that I liked was around $600, and I don't have that kind of cash to spend just on the kit itself right now. As for a radio, I was planning on getting a Futaba synthesized 9 channel. I know that I don't need that much now, but if I eventually build some of the models I want to, I will need channels for flaps, landing gear, bomb racks, etc. Plus it will be nice to not have to put in different crystals all the time. And as far as covering goes, what is a good way to learn before I actually do it? I'm not keen on screwing up on this plane.
