From the Magazine:- It would be nice to be able to say that the 4-F was the evolutionary result of a lengthy design phase, during which a prototype was built and flown, with several modified versions following that fine-tuned the design for optimum performance. In truth, the design phase for the 4-F encompassed about twenty minutes of general sketching and drawing board dimensioning! The goal was to create a simple-to-fabricate and build, almost all foam airplane that would possess good sport flying characteristics. It is an easy to fly hand-launch type aircraft, with no bad characteristics. The 4-F is clearly not even a semi scale design, but it does have a bit of a WWII fighter appearance. The 4-F was powered with a Cox .09 R/C engine, and an Airtronics RD 6000 radio system was used. While a glow engine was used in in 4-F, there is no reason why the 4-F could not be electric powered also. Throughout the design, fabrication, and construction phases simplicity was of primary consideration. The entire airplane consists of eight basic foam parts, with balsa being used only to cap the foam tail surfaces and aileron hinging surfaces.
