3Quarters

Overview

Treat yourself to a sporty low-wing model that is easy to build.

There is elegant beauty in simplicity. That is true with almost anything, but especially so when it comes to model-airplane design. Straight lines joined by strategic curves can transform a "stick" into a balsa sculpture. Randy Randolph was a master at performing this transformation regularly with his many easy-to-build-and-fly designs.

Randy created the 3Quarters to utilize the Norvel .074 and Thunder Tiger GP .074 engines that were arriving on the scene in the late 1990s. He coupled his formula of simplicity and ruggedness with sporty looks and performance to achieve a wonderful low-wing aircraft.

Construction and power

The flat-bottom, 45-inch-span wing can be built warp-free on a flat board. The rest of the model is crafted from balsa strip and sheet stock, making this a natural for first-time builders. The 3Quarters is also an excellent candidate for conversion to electric power.
