About this Plan

Rudolph. Simple Jetex sport model.

Quote: "Rudolph: the rocket powered sailplane, by Aubrey Kochman.

To the British goes the credit for the design and production of a true reaction type motor small enough to power model airplanes ranging in wingspan from nine inches to over thirty-six inches.

Although experiments had been started in 1945, these 'jet' units, which may easily be thought of as miniature 'Jato' bottles, first made their appearance in England about two years ago under the trade name of Jetex. They are manufactured by Wilmot Mansour & Co Ltd and approximately three years were spent in developing the basic idea.

The task of formulating a solid fuel that would be ex-tremely light and yet capable of generating sufficient thrust was accomplished by Imperial Chemical Co Ltd, who perfected the fuel that is now used in all the Jetex units. This fuel, although highly inflammable, is not combustible. It is harmless if handled with common sense but should not be ignited indoors or in any confined space without adequate ventilation.

The first Jetex motors arrived in this country about a year and a half ago; they are now being imported and distributed by American Telasco Ltd, who are sole representatives in the United States for the units. At the present time there are four different motors available. The smallest and latest one is the Jetex 50 which develops one-half ounce of thrust and is capable of flying models up to twenty inches in wingspan... "

* 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.
