Wee Duper Zilch. Control line sport model. Quote: "Designed around the Class A engines, the latest product of the old stunt master is an amazing performer, combining smooth pattern flying with tight and violent stunts. Wee Duper Zilch, by Jim Saftig. The Wee Duper Zilch is the latest of the line of Zilches. It is designed around the class A engine, and tests were made with a Cub .099 and .074. This ship incorporates the latest airfoil section that we have been using in our latest experimental designs. Smooth pattern maneuvers are easily executed with this ship as well as the very tight and violent stunts that are impossible to execute with most stunt jobs today. You will be greatly surprised and very pleased with this amazing ship. A stick job was first worked out to check moment arms, etc. This was abandoned as soon as it had served its purpose. The stick job had been built and flown many months before the birth of the Wee Duper. Construction of the plane is very simple. The wing is perhaps the simplest part of the whole job to assemble. It can be very nearly put together completely before gluing. Fuselage. Slightly taper 3/16 sq piece of balsa and glue rear of fuselage sides to it. Hold this in place with pins or clothespins. Add front plywood bulkhead and second ply-wood bulkhead with motor mounts in place and be sure that the sides are lined up in proper position. Allow suffi-cient time to dry before going on. Add 1/8 in braces as shown and allow to dry. Drill holes for threading of gear and add landing gear. Make sure that this is lined up perfectly before continuing. Add 1/16 in sheet to bottom of fuselage after putting in reinforcements 3/32 in sheets at rear of fuselage as shown. Thoroughly sand this whole unit, being careful not to sand top sides of fuselage where top forming block glues in, then add one coat of sanding sealer to this unit and sand lightly with fine sandpaper. Apply paper covering to this portion with thin dope and then apply two coats of sanding sealer. Sand lightly, being careful not to tear the tissue. Then add one coat of dope over complete assembly. Draw rib section, using template, on sides of fuselage in correct position, making sure that you measure down from the top of the fuselage to the center of your leading edge and center of your trailing edge. Do this on both sides so your wing will be in the correct position. Make sure that everything is sanded smooth. Wing. Slide all of the ribs onto your main spar, being sure you have included the sub-spar in the operation. Add leading and trailing edges, then glue all necessary joints well. Allow to dry thoroughly, then check for any warps. Add the reinforcing plywood..." Direct submission to Outerzone.
