AMA Plans Service Keytwo - 2006/08

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, but 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.
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 fullsize
plans for this model are available from the
AMA Plans Service. (See the advertisement on
page 183.)

Keytwo (or any other favorite MA design) by
