I've been watching this thread of some time now. I picked up one of these ARF's last summer as a project for this winter. I was going to go with an electric power system but the one I have has no battery hatch and it looked like it was going to be pain to put one in and make a nice job of it. Then I saw the new 10cc gas engine by Evolution.
It is supposed to replace a .40 to .60 nitro engine. I have other larger gas planes and love them. There cheep to operate, fly for ever on one tank and not too messy. What do you guys think? Is this enough power? Is it too heavy? The cost should be close to that of a quality electric power system. I think it mite be a good match.
