Spad's can be a heck of a lot of fun. Watched the video, and it represents the fun we have with them. I built a Spad Debonair with a flat wing and conventional gear, and flew the crap out of it. Was it a "dog"? Yes, it was. Could I fly it and do loops, fly inverted, do stall turns, half Cuban eights and have fun all afternoon? Yes, I did. So I think everybody should at least try one. They're not a perfect solution to model RC aircraft, but they are a lot of fun. And they are economical . Try one and have fun.
