Race planes of aviation's golden age have a way of quickening the pulse and misting the eye of scale modelers. For the Walter Mitty's of the Flying Aces Club there are even two Mass launch recreations of that era, the Thompson Trophy and the Greve Trophy, the former for radial-engined scale models of 30s racers and the latter for inline types.
Who isn't familiar, by now, with the Gee Bee racers, Travelair Mystery ships. Art Chester's Jeep and perhaps a few others? But how many of you have ever heard of such esoterica as the Sundorph Special, the Haines Racer: the Rasmussen Skippy, or the Rowinski racers? There were many such ships, which, because of bad timing, had luck (often fatall, or both have remained in obscurity.
A few months ago I had the good fortune to buy a two volume history of air racing (The Golden Age of Air Racing, pre-1910), published by the FAA Foundation. PO Box 2065, Oshkosh, WI 54903, an inspiring collection of articles, photographs and 3-views. All of the old favorites are discussed but so too are many of the barely remembered race craft, including, of course. Claude Flagg's diminutive racers.
The F-15 San Diego Flaggship: Flagg was the designer and builder of several race planes. many of which were based on small radial engines like the Cirrus and the Pobjoy. In 1936 he created the F-15 San Diego Flaggship around the Pohjoy seven cylinder Niagra engine, a craft so small that its elliptical wings spanned little more than 14 feet.
The plane was slated to be flown in the 1937 National Air Races by young Tony Le-Vier but was seriously damaged in an ill-fated qualifying run. Claude Flagg, ever the optimist, embarked on an extensive rebuilding program, replacing the original wing with a tapered version that incorporated larger ailerons. The landing gear was replaced with a retractable version, and a new, tight-fitting cowl crowned the engine. Finally, the little racer was given a livery of Sunburst Yellow and Robin Egg's Blue.
Although the reborn F-15 managed to set a new speed record for its class of over 250 MPH, it was once again damaged in a take-off mishap at the 1938 National Air Races at Cleveland and never raced again.
Building the model: The rebuilt Flaggship had a wingspan of exactly 13 feet, which in peanut scale produces a model with a fuselage length of nearly the same dimension - very good proportions indeed for a peanut, with lots of room for a long rubber motor.
Construction of the model is quite conventional, the principal challenge being reproduction of the dazzling paint scheme of the real airplane. Fuselage. This is built by first laying down a fuselage side directly over the plan and then constructing the second side directly over the first. Longerons, uprights, and cross pieces are all made from 1/16 inch square stock. Cross pieces are determined from the fuselage top view, except at the locations F6 (top former) to F10 (top former, where the formers are used..."

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

User commentsHere's a couple pictures of my model constructed from these plans [003, 004]. It was a very fun build. But I highly recommend to thin down the cowling extensively to eliminate too much nose weight. I used Dr. Martin's Acrylic Ink for the finish.

* 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.
