I've built the 60 size 'Bolt, some years ago, but it's still flying and going strong! You'll love this plane. Build it light, don't go crazy with the epoxy or a heavy covering. Build it to the directions and you'll end up with a light but solid plane that flies wonderfully. Mine turned out to weigh 7 1/2 lbs with retracts and flaps. I covered it in Ultracoat I may build another one this winter, all depends on what new designs TF releases.
