The Cascade Kasperwing I-80 is an American ultralight flying wing motorglider that was designed by Witold Kasper and Steve Grossruck.

It features a cable--braced high-wing, a single-seat, open cockpit, tricycle landing gear and a single engine in pusher configuration.

Its 35 ft (10.7 m) span, single-surface wing employs a special Kasper-designed airfoil that allows both normal flight and a fully controlled, completely stalled parachutal descent mode.

The landing gear is of tricycle configuration, with a steerable nosewheel that has reversed controls; the pilot pushes the right pedal to go left and vice versa.
