Fighter Fly (oz6195)

About this Plan

Fighter Fly. Rubber low-wing sport model.

Quote: "Have some real sport-flying fun with this inexpensive model. It looks like the Interceptors of the early 30's and flies like a contest model. Fighter Fly, by Sherman Gillespie.

The Fighter Fly is an easy-to-build rubber-powered sport model suggestive of the open-cockpit Interceptors of the early 1930's. Though of light construction, it will prove a durable, stable ship that will give you some fine flying pleasure. In cool evening air, the prototype was hand-wound and turned in flights of up to 32 seconds. Warm air conditions brought many flights of over 1 minute duration, with the top time to date a whopping 2 minutes and 54 seconds - out-of-sight behind some trees!

Study the full-size plans, pictures and construction notes thoroughly before laying out any parts.

FUSELAGE: Select hard straight-grain 1/16 square balsa for the basic fuselage construction. Sand all wood lightly with very fine sandpaper. Cut the cockpit sides, the wing slot pieces and the rear motor-pin receivers from medium-hard 1/16 sheet before placing the longerons and cross braces. Fit these pieces accurately as they assure a strong job. Build one side at a time, cementing all joints carefully.

Being of equal width from nose block to cockpit, the nose section is an ideal point for starting assembly of the two fuselage sides. Cut fourteen crosspieces to the proper length, as indicated in the top view of the fuselage. Pin and block the sides firmly over the top view and put in the crosspieces top and bottom. Cement and allow to dry thoroughly, then tip the rear of the fuselage down on the plans. Pull the sides together over the top view and cement at the end.

Again, it is easier to have the cross-pieces, top and bottom, cut to size and ready to put in place. Strive for a strong, accurate fuselage; it is essential for easy alignment of wings and tail surfaces.

The nose block is carved from medium-soft balsa. Drill it to receive the hard-wood thrust button, and hollow out the back as shown. Cement the block lightly to the fuselage and finish shaping and sanding. When completed to satisfaction, cement the unit permanently in place. Apply two coats of sanding sealer to provide a smooth finish..."
