About this Plan
Speedy-Q. Control line speed model.
Quote: "Winding up our series on controliners for beginners, we present full-size plans and build-it data for a contest-winning speedster. Build the Speedy-Q, by Walter Schroder and Norman Bud Couch.
To wind up the control-line model phase of our series, we bring you complete construction data on the Couch Speedy-Q, a Class D speedster which won every major Northeastern Plymouth Eliminations event in 1949. It won the Greater New York Area meet with 144.22 mph; the Connecticut meet with 135.25 mph; the Massachusetts meet with 138.50 mph, and numerous other New England contests with speeds ranging from 135.25 mph to 146.70 mph.
Our speedster is the cumulative result of many models - the best points incorporated, the weak-nesses eliminated. The main objective was a maximum strength-to-weight ratio, with ease of flying at high speed. The model shown in the photos was flown at least twice a week for two and a half months without even a minor repair, just a swipe of a wiping rag and back to work.
Believe it or not, we used a standard, stock Dooling engine - the only thing done was to file the exhaust stack flush with the outer edge of the cowl, matching its contours. A word of caution: when filing the stack, be sure to stuff it as well as the intake venturi with good clean rags, to keep filings from entering your engine.
One last design note : the hard-wood top of the engine cowl and the carved, integral rudder can and will absorb the roughest cart-wheels and turnovers without any injury whatsoever. The take-off dolly is standard Couch design, extremely simple to build. The side and top-view drawings will tal=ke care of any construction propblems. When fitting the dolly to the fuselage, be sure to compress the two prongs at least 1/4 in and indicate their compressed width..."

* 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.
