Hovey Whing Ding II

Whing-Ding II Ultralight Airplane


The Whing Ding is a super-simple ultralight airplane that was designed by Bob Hovey. The first design simply labeled “Whing Ding,” was first flow in 1971. A subsequent “improved” version followed, named the Whing Ding II. The improved version incorporated a higher seat to prevent the pilot’s feet from dragging on the ground.

Flying this bird is an experience like no other!
You climb into the “cockpit” which really isn’t….you’re sitting out front in the open like a birdman about to get airborne. The wind is in your face and behind you is the steady roar of the little 15 HP single-cylinder engine that is pushing you and your aircraft through the air.

This is off-airport flying at it’s best!

Flying this bird is reminiscent of a by-gone era of flying akin to the Wright brothers. The Whing Ding II classifies as an “Ultralight Airplane” under US FAR part 103 and hence requires no license or registration to fly! Simply find a secluded flat area, start up your engine and fly with the birds!

  • Low construction time using simple methods and no specialty tools.
  • CHEAP to build and fly! You could build this airplane for as little as $600!
  • Easily disassembled for transportation to flight site.
  • Powered by a inexpensive 15 HP go-kart engine.
  • Completely engineered drawings and material source listing (Editor’s Note: some sources now defunct).

The Whing-Ding II biplane is the ultimate in lightness and simplicity. The tail surfaces are built from 1/2 inch thick Styrofoam art board and are covered with craft paper on both sides (then coated for extra strength). The critical areas are reinforced with 1/8 inch plywood gussets. The tail boom is a simply 3″ aluminum tube filled with foam to make it resistant to buckling. The fuselage is built from 2 sheets of plywood 6 inches apart that are filled with foam. This structure serves as an engine mount and a mast support for the wings, which have two spars and are fabric covered. The prop is chain driven from a 15 HP 2-cycle go-kart engine.
