Well, I've learned what I wanted to learn. The plane has a problem, or at least some do. I've been flying R/C for 40 years and done my share of competition. Normally, when I run across a design with these problems, I can it and move on.This design has received so many accolades, that made me want to try and find all of those good points some of you are talking about. I have been flying as many 1.20 size airplanes as I can build in an attempt to find one that flies like the 30-40% er's. The one or two I've found would surprise most of you. They are oldies but goodies. But the Goldberg Sukhoi and the Goldberg Bucker Jungman biplane are awesome. I f you can find a kit for the Bucker buy it and build it, you won't be disappointed. Enough of this.
