About this Plan

Gus. Simple vintage-styled rubber sport model.

Note this model is basically a reduced size (and uncredited) version of the 1942 Ron Warring design Percy III (oz1563) many thanks to Mike Hollamby for pointing this out.

Quote: "Gus, by John Walker. This is what Stick-N-Tissue rubber powered modeling was all about just a 'few' years ago.

GUS is patterned after models that were built and flown in the late 1930's. While going through some old magazines we noted a photo of an English contest winner. Not knowing its dimensions, our model was designed for small field flying.

The guys in the 30's lived dangerously. They didn't use dethermalizers, but took their chances. Flight time was what counted. It was determined by how long the model remained in sight of the timer. It was to your advantage to persuade the timer to get into a car and follow the model. These guys went for broke.

The model is simple to construct. Select the wood for weight and strength. A little time spent selecting wood will pay in performance. Use one of the new cyanoacrylate adhesives to save time.

The fuselage on our model was covered with light weight silkspan, while the tail and wing were covered with tissue. After the covering was shrunk with water, two coats of thinned nitrate dope were applied to the model.

The nose block must fit snugly into the fuselage. If it doesn't, or it becomes loose from wear, cut a small notch around the top of the block and hook a light rubber band onto the landing gear. This will hold the nose in place.

Power consists of 2 to 3 loops (4 to 6 strands) of Sig 3/16 rubber, well lubricated. Your model might require more or less, depending upon its weight. You can carve your own prop (easier than you think), or use one of the commercial propellers available.

Test-glide the model over tall grass. Move the wing forward to counteract diving. Move it to the rear to prevent stalling. Make power adjustments by adding down and/or side thrust to the nose block. Have a good day. "

Did we get something wrong with these details about this plan (especially the datafile)? That happens sometimes. You can help us fix it.

Good catch. Will add this to the description. Thanks.

I don't wish to be unkind to Mr Walker, but this plan does not look like it was scratch-drawn after seeing a model pic in an old magazine. Rather, it looks like it was drawn up by someone who had the Warring plan unfolded and spread out on his desk next to him.

* 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.
