I have read some of your posts on supercub site. I refuse to use the site from the negative responses from some of the users on the site. I have built a carbon frame work wing using the ribblett 66 for a super cub. Jim marske did the calcs on the spar for me using the D&E data from there spars i went another 30% for safety. I know CAlkins and a few others on the cub site and if someone has a better mouse trap they will poo poo it. They like to stroke the ones in there group. I call them bolt on builders. I have not done much with my project in the last 2 years as i have been rebuilding my helio courier. I have another freind who has done some extreme stol things with the ribblett.
