Fokker D1. Free flight scale model for rubber power. Wingspan 13 in.

Quote: "Immelmann's Fokker D.1, by William Clarke Hall Jr. Make This Flying Model. Full Instructions are Given Below.

The Fokker D.1 was one of the first really effective machines to appear in the Great War. It was used by the great German Ace - Immelmann, after whom the well-known stunt turn is known, and was one of the first machines to be fitted with a synchronised gun firing through the propeller.

The model, if constructed carefully, will give an exceedingly good performance. One of the test models was fitted with an imitation revolving engine, but we advise the builder to make a fixed engine, as the flywheel motion of the other engine is harmful to the flying performance.

BEGIN the construction of the fuselage by placing waxed paper over the drawing to protect it. Place the top and bottom longerons on plan, using straight pins to keep in place. We advise you to huild two sides together, one on top of the other for exactness. When fuselage sides are dry lift off plan and wind thread lightly round the tail.

Commence putting in top and bottom fuselage cross pieces, winding thread round fuselage at each section until cement is set. You can now cut out B, C and D, and cement in place covering where indicated with smooth paper. The rearhook should be shaped from 20 swg wire. Proceed to cover whole fuselage with black tissue, with the exception of the panel under the rearhook and cockpit. Attach cross insignia.

Build engine as shown in plans carefully and fit nose button. The whole unit should be painted a dull black and cemented to bulkhead B. Cut out two pieces of A from 1/16 sheet balsa to form a two-ply cowl front. Cement a band of stiff paper round the cowl and round forward end with fine sandpaper to a finish. Now dope and lacquer white or yellow.

The machine gun is carefully shaped from a piece of soft balsa and attached to fuselage with bamboo pins. Dope and lacquer black and white. Attach windscreen and build kingpost and tailskid from 1/32 square bamboo. Note: Small hook on top of kingpost for bracing wires.

The undercarriage should he built from 1/32 square bamboo. The ends joining the fuselage must be carefully pointed and embedded into longerons. The wheels can now be made up and attached to undercarriage. Dope and lacquer undercarriage yellow and black.

The tailplane and rudder can now be traced, and cut from a sheet of soft 1/64 balsa sheet. Cover rudder on each side with white tissue and add insignia. The tailplane should be covered on topside only with black tissue. Cement both units to fuselage where indicated.

The construction of the wings is quite straightforward. The mainspars and tips should be pinned in place and the ribs traced and cut from 1/32 balsa, with the exception of the root ribs, which are cut from 1/16 in sheet balsa. Cover with black tissue all but the panels where insignia is placed, as these panels are covered with white tissue.

Wings must be carefully cemented to fuselage, and the bracing wires threaded and cemented through.

Carve the propeller from a medium piece of balsa, and sand, stain and dope to a mahogany finish. Attach hook and nose button. Note to use two small washers and bead which act as bearings. Make a loop of 1/8 in elastic and thread through fuselage to rear hook.

Glide model, and if it dives bend up elevator slightly. However, if the model stalls bend down slightly, or add a small weight to the nose.

When the machine glides evenly put a touch of oil in the propeller bearings and give 100 turns."
