About this Plan

Speedwing. Delta type flying wing sports control line model.

Quote: "If you feel tired with an impulse to make 'something out of the ordinary', then try this little flying triangle that is easily built in two evenings. Speed Wing is the outcome of a decision to construct a Delta type wing to relieve the monotony of conventional design.

By virtue of its paper dart-like shape, it never fails to catch the fancy of the public during demonstrations at the Stewarton football matches. It is almost unbreakable too, so. if you are wanting to build something quickly for your 2 cc engine, something that will be hard to bust and will always give you good fun, then try this model.

Construction: Cement the three 3/8 sheet parts of the wing, the top and bottom plywood stiffeners and the spruce rear edge together. Sand the wing to a symmetrical aeroioil section in two stages; first to taper, then to airfoil. Drill the control plate and horn to fit the wire pushrod closely and tix in place, noting the use of flexible stranded wire for the lead outs which are passed through tubes buried in the lower wing surface. Attach the elevator after cutting, as shown on the drawing, and twisting the outer portion upwards; this will cure any tendency for the model to roll inwards. Take care that the lower plywood plate tits the engine mounting lugs neatly, and cut away only just cnough of the wing to dear the engine. Make up the lower engine mounting pod, complete with 22 swg aluminium cowling and the fuel tank. Attach the engine and assemble the pod to the wing by wood screws, then add the upper balsa fairing on the top surface of the wing. When dry, dismantle and fuelproof all parts likely to be in contact with fuel or exhaust. Add the plywood fin and cover the whole model with Modelspan before doping to the desired colour.

Because this model has no fuselage to hold for a hand launch, it must be launched underarm, by gripping the fin and throwing with a 'bowling' motion. Though unorthodox, the launch is soon perfected after practice. "

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.
