Electric Kerswap (oz16051)

About this Plan

Electric Kerswap. Radio control sport model, for electric power. Wingspan 51.8 in, wing area 400 sq in.

Quote: "Gilbert Morris, Designer of the Kerswap. Gilbert Morris started building model airplanes at the age of 8 in 1933. He soon began building his own designs. His main interest was in duration flying. His early efforts were all rubber powered. He bought his first engine in 1939 and from that time on stayed with powered models. In the fall of 1941 Morris designed the Kerswap. He built three Kerswaps that winter. During the 1942 contest season he lost all three models when they flew out of sight!

Our version of the Kerswap was designed by Tom Hunt. The new version features a larger wing span, easier to cover flat bottom airfoil, simplified construction and we have converted it for electric power. We think you will enjoy this new edition of a fine old timer.

Tools and materials needed to build the Kerswap: A few simple tools and materials are needed to build the Kerswap. Experienced builders will probably already have these items on hand. Beginning modelers should gather the items listed below before beginning construction of this kit.

Building board: We recommend purchasing a balsawood building board. These boards are made of laminated balsa to produce a flat work surface, an important requirement for building a straight airplane. They also accept and hold pins very well. Other materials can make acceptable building boards. A piece of sheet rock or plywood with one sanded surface may also be used. Whatever material the modeler chooses for a building board, remember it must be flat and should be at least 12 x 30 in for the Kerswap.

Construction begins by studying the plans, parts, and instructions. The builder should understand what is to be done before committing glue to wood. This attitude towards building helps to eliminate mistakes and results in a more enjoyable and successful building project. Every model airplane kit should be built carefully. Good building practices will result in a better looking and flying model. Taking the time to accurately cut stock and pre-fit parts pays off with an overall better model.

A few important points should be kept in mind throughout construction and are essential if the model is to fly as designed.

- The model must be built true.
- The flight controls must operate smoothly with no binding.
- The model must be kept light.
- The completed model must balance where shown on the plan.

Following the instructions carefully will help to insure these important requirements are accomplished.

Vertical Fin & Rudder: Parts and materials required for this building segment Laser cut fin/rudder pieces V1, V2, V3, V4 3/16 x 3/8 balsa strip stock. 1) Cut the 3/16 x 3/8 strip stock for the fin trailing edge and the rudder leading edge and pin them over the plan. Leave them long, they will be sanded to size later. Cut a piece of 3/16 x 3/8 strip stock for the bottom of the rudder, trim the end to the correct angle, and pin to the plan..."
