Catapult Glider


Building A


These simple gliders are refined to incorporate more performance than before!

ne of my favorite parts of modeling has always been the small wooden gliders which I often fly for fun at the local field or between free flight


sessions during a meet. I compete on many levels of rubber powered freeflight, indoor flying, scale models, outdoor duration … but perhaps it’s the inherent simplicity of a glid- er and the freedom to design and experiment that makes gliders the most fun for me—not to say all gliders are simple. On one end of the spectrum is the half-gram balloon launch glider I made for the Indoor Nats in Johnson


City. On the other is the large, built-up- wing-discus-launch glider I made for outdoor competition at Palm Bay. My family, all avid modelers, recently


bought several kits of the popular 18-inch catapult gliders from A2Z (www.A2Zcorp. us/store, 720-833-9300; see ad on page 16) called Sting 18s. These gliders are a little larger than the standard 12-inch size and are perfect for the local field as well as Out- door Catapult Glider competition. They come laser-cut with all the necessary pieces and include the carbon fiber fuselage boom,


DT timer, and detailed instructions. Though very well designed stock, they were quite heavy and after making a few of them (which already flew quite well) I quickly re- alized that a few modifications would boost performance and make competitive models from these fun flyers.


Construction My first improved copy of the basic Sting


18 started with a leftover kit. I carved the modified wing using a razor plane and coarse sandpaper while making the wing
