Curtiss R3C-1 Racer - Control line scale model racer. Arden .19 BB engine shown.
Quote: "Curtiss R3C-1 Racer - the famous racing plane that held both the land and seaplane records in the 1920s... The 1925 Curtiss R3C-1 racer makes an ideal U-Control model. Its clean lines make it very fast and its proportions make it highly maneuverable. Lt Cyrus Bettis used it to win the Pulitzer Race (landplanes) on September 12 1925, with a record of 248.98 mph. The winning ship was converted to a seaplane in two weeks time for the Schneider International Race. None other than Lt Jimmie Doolittle flew it to victory at the record speed of 234.36 mph.
The R3C-1 was the last American plane to hold the world's speed record until the summer of 1947, when it was regained by a special Lockheed P-80R (623.8 mph average).
Construction: Note how the power unit is detachable. It is held in place by two four-forty machine screws. The wings are detached at lower wing and strut intersection, with two 3-48 machine screws and nuts. The ignition, gas tank, landing gear, and motor are all accessible, with the removal of these four screws. The controls may easily be inspected. Make firewall at station 2 out of 3/32in plywood. Assemble top and bottom fuselage blocks and glue them lightly together..."
Did we get something wrong with this plan? That happens sometimes. Help us make a correction
* 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.
