The Aces High Cuby is a family of Canadian single engine, high wing, strut-braced, light sports planes with conventional landing gear that was marketed for homebuilding by Aces High Light Aircraft of London, Ontario.

The aircraft design was available in two versions, the single-seat Cuby I and side-by-side two-seat Cuby II. Aces High went out of business in the 1990s and the kits are no longer available.

Development

The Cuby fuselage is constructed from welded 4130 steel tubing, covered with aircraft fabric. The wings are built around an aluminum spar and D-cell and also fabric-covered. The conventional landing gear includes bungee-suspended main wheels and a steerable tail wheel.
