This is the exact same Lazy Bee Float design that we used to sell in the old days, except now the kits are laser cut. It may be immodest to say so but they could not be improved upon. I am really proud of these floats. Easy to build, easy on-and-off, and they fly beautifully. Take-offs and landings are super short... no extra power needed. They are a great way to get hooked on float flying. Truly fun. They work with all the Lazy Bees and Lazy Bee Specials (40", 48", or 50" wings). PS: They make great skis for winter flying!
