About this Plan

Klipper. A simple control line trainer model for 1 - 1.5 cc engines.

Quote: "AFTER breaking up several kit models, I decided that it would be cheaper and easier, in the long run, to design a trainer which would withstand the hard knocks and crashes which are inevitable when learning the basic principles of how to successfully fly control-line.

The following requirements were borne in mind - ruggedness, simplicity, quickness of building and cheapness. Klipper fills all these requirements and has proved to be a strong, stable trainer.

A Frog 149 was used in the original, but any 1-1.5 cc engine is suitable, provided the distance between the inner wing ribs W1, to which the engine hearers are cemented, is varied to suit. Similarly the position of the tank may also have to be adjusted.

Construction Pin LE and TE over plan, slots in line, the TE being raised 9/32 in using scrap balsa. Cement in wing ribs. Whilst this assembly is drying, add lead-out tubing to port wing tip, and weight to starboard wing tip. By using two thicknesses of in. sheet, these can be easily recessed to take the tubes and weight, and then cemented together.

Cement horn into elevator. Remove wing from plan and cement wing tips in position. Recess LE for engine bearers and cement bearers to LE and ribs. Cement packing piece between engine bearers... "

* 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.
