Big Guff - Radio control model. Winner of the 1938, 1939 and 1940 Nationals. Note this is not a fullsize plan, this is a scan of the drawings as they were originally printed in the pages of the magazine, in 1940.
Quote: "RADIO control of a model plane is a new and fascinating hobby. Every modeler dreams of controlling his own models, and it is hoped his enthusiasm will be livened by the presentation of this thoroughly proved radio-guided model. Over one hundred and fifty flights have been executed with the equipment described, so only those things which have been tried and found successful will be included. In many of these flights the plane was returned to within a few feet of the take-off - and that's a real thrill, especially when you are doing the controlling.
The present ship carries two controls, rudder and elevator. It is suggested, however, that a rudder control alone is an adequate beginning. Complications arising from two controls are apt to be discouraging. Interestingly enough, the 1939 Nationals were won using only the rudder control. Simplicity is the keynote throughout the entire construction. Most modelers yearn for the supercomplete complex radio job. Try a simple one first.
Several years of experimentation have shown that the ship itself is as important as the radio unit it carries. Naturally, the weight must be carried easily. The glide and power flight speeds should be nearly equal - to give the same response to control under both conditions. Side-area considerations result in good turns to right and left. And finally, properly sized control areas are indeed essential.
In spite of its largeness this ship is powered with a 1/5 hp Brown motor. It may be noted the ship has the same characteristic fuselage shape as the author's Guff. This seems to aid the spiral stability..."

* Credit field
The Credit field in the Outerzone database is designed to recognise and credit the hard work done in scanning and digitally cleaning these vintage and old timer model aircraft plans to get them into a usable format. Currently, it is also used to credit people simply for uploading the plan to a forum on the internet. Which is not quite the same thing. This will change soon. Probably.
This model plan (like all plans on Outerzone) is supposedly scaled correctly and supposedly will print out nicely at the right size. But that doesn't always happen. If you are about to start building a model plane using this free plan, you are strongly advised to check the scaling very, very carefully before cutting any balsa wood.
