Cavorite is a word invented by H.G. Wells in his 1901 book The First Men in the Moon. In the book, it's a metal alloy, created by a Mr. Cavor, which, when cool, is able to cancel out the effects of gravity on anything it covers. Thus, Cavor uses it as the heart of a fin-de-seicle spacecraft, opening and closing windows in a shielding mechanism surrounding a Cavorite sphere and effectively controlling the effects of gravity itself as a propulsion system. Lots of fun, and an appropriately anti-gravitational name for a vertical-lift five-seater like this, the Cavorite X5.

Once in forward flight, the wings close over, restoring the aerodynamically-efficient shape of a standard wing. Horizon claims that with an LS V8 engine on board and a relatively modest battery system, the Cavorite X5 will offer fully-loaded ranges up to 310 miles (500 km) with 215 mph (350 km/h) cruise capability and the ability to fill up and fly home on pump gas. Unladen with cargo or passengers, it'll fly more than 625 miles (1,000 km).
