Hey Double D...I sheeted my canopy with 1/16th balsa. Gator said he had trouble with his breaking up there. Too many inverted landings I think. Easier to cover too. I also lightened the ribs in front of and behind the spar, saved a bunch there I think. I still just have that one day flying on mine, I'll try and get out wed or thurs. When are you guys getting out next?
