Man, If it were not for Dave having drawn up and kitting these awesome wings, I would have been begrudgiingly building my 11,000th set of foam wings and stabs. The weight savings is a great benefit and the jig really makes for a very straight wing. Most important to me is that I get to build a beautifully thought out wing. I love building at least as much as flying. I have missed it a lot these last several years. When I saw Jeff's Lightning and Dave Snows wings, I had to dive back in!
