About this Plan

Focke Wulf Stosser. Free flight scale model for rubber power.

Quote: "As a subject for a rubber-powered flying scale model, the Focke-Wulf design has a lot to commend it. The old aviation adage that a plane that looks right, flies right, is borne out by the Stosser. The combination of the gracefully contoured swept wing, highly distinctive tail group, and a fuselage and landing gear of smoothly flowing yet functional lines, come together to offer one of the most attractive parasol-type airplanes ever to come off a drawing board. A soft silver finish setting off the black registration lettering caps the Stosser's appeal.

Construction, while not difficult, employs sheet fill between stringers in much of the forward fuselage, and requires a little more time on the part of the builder. The finished product, however, rewards this slight extra effort with a very rugged model, one that will come through relatively unscathed in prangs that would bench a more lightly constructed flying machine. At an all-up flying weight of 3 oz, the Stosser is heavy enough to groove well in flight, yet sensitive enough in good air to hitch a ride in passing thermals.

The building of the Stosser follows conventional practice, except for the fuselage, which is built in two main parts. The fuselage was built this way to accommodate the landing gear instal lation, and to facilitate the shaping of the fuselage at the radius just aft of the engine cowling. The radius simulates the cooling air exit from the engine compartment and is a distinctive feature of the Stosser.

Build the fuselage sections using the familiar keel and former method. Stringers are laid on alternately, side to side, using care to maintain alignment. Use stringers that are firm but light. Cracking a too soft stringer in handling the finished model can be avoided by careful wood selection, yet heavy stringers that shoot the weight of the model up sharply should be avoided. It's a kind of a tightrope that rubber scale modelers should learn to walk.

Before the final few upper forward fuselage stringers go into place the wire cabanes are installed. The forward cabane is sewn with thread to its mounting former and the rear cabane is secured to its former via small balsa blocks grooved to fit the wire. Baking soda and a cyanoacrylate are used to fix the cabanes in place.

The entire engine cowling and forward fuselage are sheet filled to the extent shown on the plan. The balsa used for fill should be soft and very light 1/16 sheet... "
