That's a really informative video. Thanks for posting. Somewhere there I saw an indication that he was going to post a complete copy of the video on his website, but I couldn't find it. There is a text and photo based description of it all on his site, but it doesn't include the flaperon installation. Never tried to copy a youtube video, but I think I'll try it with that one. I don't own a Radian right now, but can see the possibility of smacking the last of my flyable TD airplanes and needing a quick replacement to keep flying. I noticed, when flying the Radian of an acquaintance that it did indeed have a severe tendency to want to loop under full power. Now I know why. Anyway thanks again.
