SR, I think this is more about the weight/design of that plane? Not sure the 115 is going to be a lot of help? What does it weigh? To help this plane out, it would need to be significantly lighter the the DLE 20 - which is at something close to 29oz. all up? If not, he's spent much more money - and it's still going to be overweight/shy of wing area when considering 3D work? -Al
