Comper Swift (oz3101)
About this Plan
Comper Swift. 20 inch span FF scale rubber power, model racer.
Quote: "Full size plans for a simple rubber model of this famous King's Cup air race machine. Comper Swift, by Ron Warring.
THE first Comper Swift appeared in 1929, built by the short-lived Comper Aircraft Company of Hooton, Cheshire, and the design was a popular favourite for racing in the early 1930s. Although only 37 Swifts were actually built, it appeared in two forms - one with a 90 hp Pobjoy Niagara radial engine, and the other with the 120 hp in-line Gipsy III. Two of the former type survive to this day in this country, whilst a Gipsy engined Swift is still believed to be airworthy in Australia.
When it appeared, the Comper Swift was claimed to be the smallest light aircraft in the world, and also the fastest. Its price, with Pobjoy engine, was £550. Enthusiastic owners bought it chiefly for racing, where it was invariably handicapped near the 'scratch' mark. Our model is based on the Gipsy-Swift owned by the then Prince of Wales, which placed second in the 1932 King's Cup Air Race at an average speed of 155.75 mph. There were, as a matter of interest, eight Camper Swifts in this race out of a field of 42.
For best performance, choose the lightest sheet available for the model. The fuselage sides are cut from 1/16 in sheet of normal straight-grain variety. The fin and tailplane should be cut from really light quarter grain 1/16 in. The decking and bottom of the fuselage are covered with 1/32 in sheet and since this has to be bent into a curve, the selected sheet for this should not be quarter grain.
Make a careful tracing of the exact shape of the fuselage sides from the plan and cut two identical pieces from 1/16 in sheet. Similarly transfer the former drawings to 1/16 in sheet and cut out. Mark the positions of the formers on the sheet sides and begin assembly with formers 3 and 4..."

* 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.
