About this Plan

Charger. Control line stunt model.

Quote: "This 049 swept-wing stunter will fly on long lines because of relocated off-set engine. Does full AMA pattern. Charger, by Jim Mayfield.

FOR THOSE who want something really different yet capable of doing the AMA precision aerobatic pattern, the Charger is it! Charger was developed as an experiment to test an unusual thrust arrangement in a competition, precision, stunt design. The thrust idea isn't original, but was borrowed from Charles Mackey and Bernard Ash, who tried it years ago. As a competition machine, the ship is not quite up to form, but for sport and fun flying it fills the bill. With the engine and tank mass near the CG, Charger turns instantly! As would be expected, there is no line tension problem.

Construction begins with the ribs. Using a new sharp blade, cut out all the ribs, making R-1, R-7 and R-13, jig ribs. On the jig ribs, cut the rib shape in a dashed fashion so the jigs may be trimmed off easily. Ribs 2A, 3A, and 4A, for the motor mount and center sheeting, should be self-explanatory. Cut the trailing edges, leading edges and spars to length. Cut out the combination motor, tank and bellcrank mount, and drill engine mounting holes, tank overflow hole, and bellcrank mounting hole.

For a true warp-free wing, jig-build it on a flat warp-free board and then stress-relieve it. The jigs are shown on the plan as past of certain ribs. Pin jig ribs over the plans, on the building board, and build as much of the wing as possible before removing it from the board.

Slip the leading edges and spars through the jig ribs and pin them in place. Starting at the tips, and work-ing toward the center, slip the ribs in one at a time, horizontally between the spars. Twist ribs vertically, locking them into the spars, and slide toward the tip and into place. Pin the ribs to leading edge and spars..."

Notes

* 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.

Scaling

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.
