AT Interceptor (oz14430)

About this Plan

AT Interceptor. Control line sport model, for twin .049 engines.

Quote: "No need to give this beauty a build-up - she's strictly an All-American champ who will keep you running in circles. AT Interceptor, by Walt Hughes.

Designers of full-scale aircraft, limited by practical things such as the size of the pilot, location of engines, oil coolers, etc, cannot always make the outline of the airplane to their liking. The AT Interceptor, on the other hand, is a model plane designed primarily for artistic lines with no regard to practical limitations. Details borrowed from the P-38 and Black Widow Nightfighter are combined to the best advantage and a simple paint job accentuates the slim lines and carved fuselage. Rockets mounted below the wing and 40-mm cannons in the nose of the fuselage add realism.

Two engines operating from one fuel tank are a special feature presented here for the first time. This is made possible by using a Jim Walker pressure system to force fuel to the inboard engine, and fuel regulators keep the outboard engine from getting too much fuel. With this arrangement one engine can be started and allowed to run on the ground for several minutes before the other engine starts, but both engines will quit within a few seconds of the same time when the tank runs dry.

Conventional twin-engine models often run more than half a flight on one engine. Flight characteristics are surprisingly good for a semi-scale model. When balanced as shown, the AT Interceptor is steady enough to fly two feet above the ground and will fly reasonably well on only the outboard engine.

The pressure fuel system shown is very good for modelers who hope to do a lot of flying, and must be kept in gdod operating condition. Modelers who have not previously used one in a single engine ship can stick to the metal tank installation given in separate details, if desired. No hatch is required in the fuselage and less work is involved through the wing and engine installation for conventional type of metal tanks.

Start construction with the wing so that the fuselage and booms can be fitted as they are built. Cut out four 1/16 x 3 x 13-1/2 inch sheets of balsa for top and bottom wing covering. Cut triangular pieces to fill out trailing edge to size shown and glue parts together. While these sheets are drying cut out the ribs.and plywood spar joiner..."
