I don't know about the building part, the Moth isn't really an easy build but I did one, a 66 inch from an old kit builder in the UK, Percision Balsa. It was perhaps one of the smoothest flying planes I have ever had. I sold it a couple years ago when I moved here from Calif. so it wouldn't get busted up in the move. It's one of the only planes I have ever had that I miss. The plane made me look like a much better scale pilot then I really am. If you have some help doing the build the plane is outstanding!!! I think the other warbirds I mentioned are a much easier build though.
