About this Plan

Miss San Diego. Four Foot Westerner. Free flight power sports model.

Quote: "Here's a Little Gas Model that Has Every Desirable Quality - Small Span, Small Engine, Unusual Stability and a Big Performance. Miss San Diego by Elbert J Weathers.

DUE TO the present trend towards the smaller type gas engine, and the many inquiries as to plans received by the writer in the last couple of years as a result of photos in 'Gas Lines' columns, we take pleasure in presenting the data for constructing the small parasol type gas model, Miss San Diego, which was one of the very first small gas models to be built in the United States and powered with an engine of less than 5/8 in bore. The parasoled wing makes the little plane very stable and assures for depend-able performance.

The ship performs beautifully with an inverted engine installation. Almost any of the popular small type engines can be easily adapted to this gas job, by merely altering the de-sign of the metal mounting plates, which are located on the wooden beams, Whatever the engine make might be it should be inverted for maximum flight performance.

On several occasions it has flown over fifteen minutes on a forty-sec-ond motor run, and has a slow, lazy circling glide alter the motor cut. Its flight abilities are most agreeable for contest flying.

Specifications Wing Span 4 ft. Wing Area 252 sq in. Wing Loading 64 lb/sq ft. Max Wing Chord 6-3/4 in. Overall Length 31-1/4 in. Stabilizer Span 19-1/2 in. Overall Height 10-3/4 in, Tread 8-1/2 in. Weight, Ready to Fly (With Engine).... 1 lb 2 oz.

Enlarge the drawings to full working size as the first step, making use of the dimensions as given on the assembly drawing. All the balsa used is to be of firm medium-hard variety, unless noted otherwise.

Fuselage. Begin the construction with this unit. Build two side frames of 1/8 in square balsa, using wood which is very firm, especially for the longerons. Fillers of 1/16 in sheet are put in each frame at the front. Build the frames together in the usual way, pinning each up-side-down on the work table..."

Quote: "Here is a full-size PDF plan and the accompanying construction article for the 'Corn Cob' Elf-powered, 48-inch wingspan Miss San Diego, designed by Elbert J. Weathers and published in the October 1939 issue of Model Airplane News. I used the given 24 in half-span as a metric to scale the full size plan."

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.
