Check the picture I previously posted above. I went float flying today with that gentleman and his aircraft. The good news is he missed the dock and the boat, the bad news is the water was next while inverted. He said he previously was having some trouble with elevator authority.
That was, and I emphasize WAS, his fourth edition of that design. I got to see the guts after the fact and a lot of the aircraft was built with epoxy/glass sheet, including ribs, capstrips, sheeting. Some carbon fiber was also employed. Interesting construction.
