Stunt Champ (oz2142)
About this Plan
Stunt Champ. Control line model, for Fox .35 engine.
Quote: "International Stunt Champ. By Lloyd W Curtiss. Winner of Air Trails Perpetual Trophy. Top Aerobatic ace at Plymouth's 6th Internationals.
If you want a realistic-looking model that will stunt like crazy, this is it. This model won the Air Trails Stunt trophy at Plymouth's big sixth International meet. Its realistic appearance and clean lines also won a high position in appearance points. The original model was cream with red trim and a black pin stripe. It has a combination of features from many other history-making stunt planes.
Flying this model is a real challenge to any stunter. It has a lot of tail and flap movement for sharp corners and if you ease her around with a steady hand it is very smooth. With the landing gear in the wing and a turnable tail wheel this plane has always responded to an almost perfect take-off and landing. By doing an inside loop, when the tank is about dry, you can cut the engine any place in the circle and land it right in the judges' laps.
Landing this plane is an art. Because of its weight, after the motor cuts it glides very fast. If you ease her down slowly and touch the front wheels first, instead of all three, you can get a very realistic looking landing. This plane can really take the rough treatment too. It is built to 'take it.'
Construction begins with the wing. Cut the main spar from medium hard 1/8 sheet balsa. The top is straight but the bottom is tapered to produce a slight angle of dihedral. The plywood reinforcement pieces for the spar are from 1/16 sheet plywood and glued onto the spar. Mark off where the ribs will be glued on both sides of the spar, and cut hole for bellcrank. The ribs are all 1/16 sheet. Make plywood forms of the biggest and smallest ribs and then cut out as many pieces, a little larger than the ribs, of 1/16 sheet as there are ribs.
Then stack as follows. One plywood form of smallest rib, next 1/16 sheets, then plywood form of largest rib, then 1/16 sheets, then plywood form of smallest rib. Clamp them all together, carve them out and sand. Saw the stack in two on the line where the spar will be. Cut 1/16 off from both edges of the center ribs to make up for 1/16 plywood reinforce-ments. Cut holes in inside wing ribs for leadout wires."

* Credit field
The Credit field in the Outerzone database is designed to recognise and credit the hard work done in scanning and digitally cleaning these vintage and old timer model aircraft plans to get them into a usable format. Currently, it is also used to credit people simply for uploading the plan to a forum on the internet. Which is not quite the same thing. This will change soon. Probably.
This model plan (like all plans on Outerzone) is supposedly scaled correctly and supposedly will print out nicely at the right size. But that doesn't always happen. If you are about to start building a model plane using this free plan, you are strongly advised to check the scaling very, very carefully before cutting any balsa wood.
