I'm new to rc u but have been flying model airplanes for over 25 years.In order to keep my interest in the hobby going strong I decided to start flying multi-engine aircraft. I started with a scratch-built F-82 Twin Mustang, which I still fly. I then Put together a V.Q. Models A-26 Invader and I am currently working on an old Royal B-17 (About 85% finished). I'm debating on which medium I should use on the fiberglass cloth for the finish(Epoxy vs. Zap) I'm leaning toward zap to keep it light. If anyone is interested in Pics of it let me know.
