The Wing Ding was conceived by R.W. Hovey as a simple, easily built and easily Dismantled (for ground transporting), ultra light homebuilt airplane. The little design makes an intriguing peanut scale model. As a basic design, it has some drawbacks as a peanut. First, the motor base and allowable propeller diameter are too small for a rubber powered model. Second, it is a pusher configuration, and might be hard to balance. Bill Brown's C02 engine, the A-23, makes the Wing Ding a real possibility. It will swing the right diameter propeller, and the tank system can be installed so that there is a good chance of balancing the model.
The full-size airplane has a built-up, plywood-covered, forward fuselage body with an aluminum tube tailboom. The tail surfaces on the prototype were foam core with cardboard covering, although this has been replaced since the early flights with a built-up fabric covered empennage. It has wire braced, fabric-covered biplane wings and conventional, tail dragger type landing gear.
The model was built to resemble the early prototype version, so it uses sheet balsa tail surfaces. Before the model was covered, there were doubts that the tail was large enough and light enough to allow good flying characteristics. A larger, built-up set, of flying tail surfaces was constructed. However, the model was test flown with the scale-size balsa sheet surfaces, and it flies very well. The high thrust line of the engine tends to hold the nose down under power, so the powered portion of the flight is relatively fast, while the glide tends to be considerably slower
