About this Plan

TD Coupe. Free flight gas cabin model. October 1936 Model Airplane News.

Quote: "UNDOUBTEDLY many of you have been looking for drawings of a gas model that will fly beautifully, is easily built, can be carried to and from the airport conveniently, and last but not least, does not cost a fortune to build.

As for performance, this model flies at a fair rate of speed, climbs at about a 30° angle and has a glide of about 15 to 1. It is also built easily enough so that an experienced builder of rubber-powered models will have no trouble with the construction. The wing is removable, so that the model can be carried in the back seat of a sedan. Since Airwheels and silk were used, the cost was about $7.00, less motor. Using wood wheels and bamboo paper, the price can be cut in half.

The model has a wingspan of 64 inches and an overall length of 47 inches. Ready to fly, its weight without cowling is exactly three pounds. The original model has now made 82 flights with absolutely no repairs outside of a few broken propellers and patches on the silk. It is practically crashproof having hit an office at an airport, a windbreak of trees, a concrete watering trough and a barbed wire fence. The pictures of the completed model were taken after the 46th flight.

Before beginning construction, study the drawings carefully and read the entire article. The wing, tail, and fuselage will have to be drawn out full scale. Use either a pair of dividers or follow the dimensions on the drawing. If a more accurate pattern of the wing tips and curved sections of the tail is desired, lay out 1/4 in squares on the drawings and 1 in squares on your full-scale drawings.

This plane is designed for and was flown by a Baby Cyclone. This motor is perfectly satisfactory, although other motors may be used with a change of the motor mount. Take your time and be sure every piece is perfect before proceeding to the next. Be especially careful that the wing and tail surfaces do not become warped. Use plenty of cement. Go over every joint at least once or twice until you are sure of a perfect cement joint.

Begin by building the stabilizer. The material for the ribs is 3/32" x 3/8" strip balsa. Cut the pieces to correct lengths and then punch out each with a 1/4" hole and assemble on the dowel. This is now placed over the drawing. It will be necessary to elevate the leading edge 1/16" and the trailing edge 3/32". Put these in place as well at the center rib which is made of 1/4”x 3/8" balsa. Pin or weight down the entire assembly and cement. Fill in the center section with 1/16" sheet balsa as shown..."

Note this is not a full size plan, it is a scan of the pages as originally printed.

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.
