Keytwo
A low-wing design with a sporty flair that will appeal to a broad range of modelers.
The late L. F. "Randy" Randolph had a knack for designing easy-to-build, unintimidating models. Almost any of his designs would make a perfect first built-up model, and the Keytwo is an especially intriguing subject.
Most of Randy's designs were sized for 1/2A engines, but the Keytwo was designed for use with a .20- to .25-size power plant and is a more stable flier in rough air. It is a low-wing design with a sporty flair that will appeal to a broad range of modelers.
The all-sheet-balsa fuselage structure is durable, easy to assemble accurately, and roomy enough to accommodate almost any radio-control gear. The built-up constant-chord wing is easy to put together without warps on a flat building surface. Practical tricycle landing gear makes landings easy and fun.
Features:
- All-sheet-balsa fuselage: durable, easy to assemble, roomy enough for radio-control gear
- Built-up constant-chord wing: easy to build on a flat surface and resistant to warps
- Tricycle landing gear: practical and forgiving for landings
If you are contemplating your first building project, the Keytwo would be a great choice. The article and plans for this design were presented in the December 1989 MA, and full-size plans for this model are available from the AMA Plans Service (see the advertisement on page 183).
You can find the construction article for the Keytwo (or any other favorite MA design) by searching AMA's Digital Archives, a Members Only feature of the AMA website, at www.modelaircraft.org.
A complete bill of materials is included with this set of plans.
