About this Plan

Rambler. CL Team Racer. 1954 US Nationals winner, for Fox 29 power.

Quote: "Nationals and Mirror winner, 32 winning heat races in the last 11 contests, is the scorching record turned in by this great racer. For mad engine doctors, details of reworked Fox .29, next page. This, gentlemen, is final word in team articles. Winning Team: the Plane, by George Moir.

The 'Rambler' team racer is the result of experiment, improvement and practice over a period of 18 months. The Rambler has six special features, built into it after much thought and testing, some of them serving a dual purpose. These are not all original ideas, but ideas gained through talk-ing with other team racing enthusiasts. An analytical rundown may be helpful:

1. Anti-siphon cover over filler and vent cube.
2. Use of speed type tank. Located top of tank 9/16 in above center line needle valve for smoother engine run in flight.
3. Drag wheel to keep plane heading toward outside of circle and permit quicker stops.
4. Use of laminated formers for lightness and added strength.
5. Off-center wing. Inside wing (control wire side) is 1-1/4 in longer than outside wing. This gives more lift or the inside wing and permits smoother flying.
6. Soldered top front vent tube with .040 hole drilled in the inboard side serves dual purpose: (a) When tank is filled, fuel will squirt away from plane and mechanic; (b) The restricted hole forces fuel into fuel line and venturi with first manipulation of the fuel pump and permits mechanic to start flipping prop at once. No waiting for tank to fill or for priming. Note: If you use bulb method, make vent hole larger.

After two seasons of tough team racing at all the major contests in the East (New York, Delaware, Maryland, Pennsylvania and New Jersey), these features paid off, as you shall see. Out of 48 heat races, this plane has 43 first places, four second places, and one third place. In 15 ten-mile races, this plane has taken nine first places, three seconds and one fourth. That is an average of 94 per cent in heat races and 70 per cent in ten-mile races.

To win races, there is a lot of necessary experimentation with fuels and props, also with getting the pilot to make spot landings. Don't forget, during the race the pilot is a busy man. Some of the pilots forget that the shortest distance between two points is a straight line; they do it the hard way, low on one half the circle and high on the other half. Learn to fly in a groove. It's easier on everybody, including the timers.

Have the pilot keep in mind the pre-determined spot at which he should land. Have the mechanics space themselves at a 20 ft radius around this spot, so one man will always be ready to start pit work, should pilot miss the precise landing point. Also have one mechanic count laps so he can signal pilot when to land for pit service. Allow two laps for the pilot to get ready for a safer landing. Never let tank run dry in flight..."

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.
