Full Lotus floats might not mean much to most aviators, but the latest model of the inflatable, retractable-wheel amphibious landing gear is toughened up to handle gravel, dirt and grass as well. Designed for aircraft up to 1,450 lb, such as the Kitfox and other light sport aircraft, they can be seen at Oshkosh. The versatile, plastic-shell floats are available now.
