Klipper (oz16535)

About this Plan

Klipper. Radio control sport trainer model. Wingspan 45 in, wing area 290 sq in. For .09 - .15 engines.

Discontinued kit from SIG.

Quote: "The Klipper, quick and easy to build, is good for flying in confined areas or as an all-round sport model. We recommend a larger model such as the Sig Kadet (oz2950) as a first beginner's trainer, but the Klipper can be flown without trouble by relatively inexperienced pilots with a low number of RC flying hours.

For best results, install 3 channel equipment in the Klipper. One or two channel equipment can be used with less flexibility in control. Also you can install 4 or more channel equipment and use only 3 of the channels. The fuselage is large enough to carry a standard battery pack and standard size servos.

This kit is arranged so that no separate full-size plan is needed. The center section of the booklet does show some full-size patterns which will be helpful during construction. A preliminary study of the instructions and drawings of the construction steps will make it clear where several building operations may be accomplished at the same time While one part is drying, another part can be started. References to right and left refer to your right and left as if you were seated in the cockpit facing forward.

Cut all long pieces of balsa first, followed by medium lengths, before cutting up any full length strips into short pieces. Remove die-cut pieces from the sheets carefully. If difficulty is encountered, do not force the part from the sheet. Use a modeling knife to cut it free. Leave parts in the sheets until needed in construction.

A jig saw is best for cutting out the printed sheet parts. Cut just outside the lines, leaving all of the line on the part. When fitting into place in the structure or joining with an adjacent part, use the sanding block to bring the edges to an exact fit. If an X-Acto knife is used, don't cut too close to the lines but leave enough margin to true up and finish the edge with a sanding block. It is easier to cut at an angle with a knife so more tolerance may be needed for final fitting with a block.

A piece of Celotex-type wallboard makes a handy building board, into which pins can easily be pushed. Lay the building board on a table with a flat and untwisted top. Pins can be pushed through all pieces of balsa in the kit without any lasting harm. The holes will fill during sanding and doping..."
