About this Plan

Gondolier. Pod and Boom. Free flight gas model, a twin boom design.

Quote: "This month's model by Paul Lindberg. An easily built fuselage of the gondola type is a feature of this gas model. Its wings are of full cantilever construction. An efficient flyer.

ITS motor purring at two-thirds throttle, the model takes off in a flash and starts to climb. The climb is steady and steep as altitude is the main objective to insure a maximum amount of gliding time. It levels off and then swings out in a long, graceful angle.

That is what you can expect to see done efficiently many times after you have constructed this month's model. Designed to save the builder many hours of work. the model has a simplified plan which will facilitate construction. Building time is saved particularly in the fuselage design. Another of the model's features is the full cantilever construction of the wing. By increasing the plans four times the size shown, you will have a model identical with the one we constructed.

Construction of Fuselage. Careful study of the plan before construction is begun will assist materially in reducing the hours necessary for turning out this unusual fuselage. The fuselage, it will be noted, resembles a gondola in design. Formers are made from 1/8-inch sheet balsa. Vertical members are 1/8-inch square balsa. The stringers are 1/16 x 1/8 inches. Ends of the stringers to be placed at the front of the fuselage must be soaked in water and shaped because of the abrupt curve at that point in the design.

It is easiest to attach the stringers by placing the finished cross-sections of the fuselage top-side down on a flat surface. Motor bearers should be made of a hard wood and cemented securely in place. The balsa cowling may prove difficult but patient work will yield a good job,

Wings and Tail Assembly The wings should be built in two sep-arate panels on a flat surface. When completed, block the tips up until there is a dihedral of four inches. Then glue the center section in place, reinforcing heavily. A few 1/8-inch square balsa strips may be added along the wing for additional strength.

The tail booms should be of a strong grade of balsa, preferably 1/16-inch sheet basswood. Spacers are placed along the booms to strengthen the assembly. Sand the corners of these to a small radius, as shown in the cross section plan, and apply several coats of dope for more strength..."

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.
