About this Plan

Two for the Show. Control line biplane stunt model, for 1/2A power.

Quote: "Tiny, quiet, small-site control-line stunt practice plane is 049-powered, yet reacts like a big 35 job on longer lines. 'Two For The Show', by James A Wilson.

Everybody loves a biplane, but so few really fly well - at least in the control-line stunt category. Most flop around in the maneuvers, always seeming to be on the verge of stalling clear out of the air. Very few have that 'flying on rails' look.

'Two For The Show' flies like the conventional stunter with its small frontal area, long nose moment, and large stabilizer. A good power plant helps too. The Cox Medallion or a Tee-Dee fitted with a Medallion intake and carburetor assembly will supply the power necessary for good maneuvers.

We would like to put in a word, or rather several words, for 1/2A flying. It's cheap and requires smaller areas to fly in. Best of all, the 1/2A isn't so noisy. Those large 40's and 60's may sound like music to our ears, but our neighbors don't seem to appreciate them. In fact, they have managed to get us thrown out of many flying fields because of too much noise.

Good performance can be obtained for 1/2A's if a few rules are followed: use good fuel and keep everything clean. Keep weight down and use a good engine.

Start construction of this model by cutting out all the parts. Use medium soft balsa, as the finished weight should be kept to 4 to 6 oz. Next, build the fuel tank. We like to build our fuselage around the tank to avoid cutting and chopping later. However, don't bend the curve in the filler tube yet.

Epoxy glue is a boon to the modeler. It puts things together to stay, so use some to stick the mounts to the fuselage sides. When this is dry, glue the tail end of the sides together; slide the tank tubes through the holes in F-1 and the inboard fuselage side. Slide the 1/16 sheet between the mounts and tank, and then epoxy everything in place. Bend up the gear, and epoxy it between the two B-2's. When this has set up, epoxy it into position in the fuselage.

The remainder for the construction is very conventional. The bulkheads, stabilizer, and elevator assembly can be added, followed by the bellcrank and controls. The wings can next be built and installed, but do not add the struts yet. Top and bottom fuselage sheets and blocks, and rudder can be put on. Sand the entire airplane with 320 wet or dry, followed by 400 - use both dry, of course..."
