About this Plan

Guff. Free flight gas model.

Quote: "An easy-to-build record-breaking that won seven contests including the Junior Aviator Air Races, and placed in eight others.

We first heard about Guff after Walter Good fliew it to first place in the 1938 Scripps-Howard Junior Aviator National Air Rates. And we have been hearing about it ever since. For instance, Pete Dillon, winner of the duPont Trophy for weight lifting, told us that in his neck of the woods there was one gas job that could give the rampaging Zippers (oz387) a run for their money. After seeing Guff perform at the Nationals, we were inclinned to agree with him.

Guff is a standout model. Its construction is a beginner's delight, for one of Good's chief aims was structural simplicity. The fuselage is rectangular and is covered with sheet balsa. The nose and motor mounting are amongst the simplest we've yet seen.

Guff is characterized by an an almost straight up climb and a flat glide, with soaring capabilities. It incorporates an uniusual amount of down thrust (8 degrees) combined with a high lift wing and short fuselage..."

Here's the original plan as it appeared in the June 1940 issue of Air Trails Magazine. Walt Goods' Guff was the open class record holder at the Akron Scripps-Howard Races in 1938. Span is 72in. Second page describes the ignition system construction, and has a wing rib template.

Notes

* 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.

Scaling

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.
