This is the exact same float that is used for the Lazy Bee (as you can see in the pic); it works beautifully with Speedy Bees! This float kit design has not changed since 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 the Speedy Bee and all the Lazy Bees --Original or Special (40", 48", or 50" wings). PS: They make great skis for winter flying!
