About this Plan

Der Jager. Radio control scale model for .40 power.

Quote: "Der Jaeger has become a classic in biplanes, and this great model is no exception - by Floyd Manly.

WELL, Model Airplane News has to take direct credit for this design. In the November 1984 issue they ran a page titled 'Planes Worth Modeling,' with four-views of the Der Jaeger that just begged to be built. Because I am a bipe nut and I had recently seen a 1/4-scale Der Jaeger that I liked, I was hooked!

The four-views were helpful in laying out my plans and I came up with a wingspan of 48 inches, or approximately 1/5-scale. I figured that a Fox .40 I had on hand would fill the power requirements.

Before I get into the building sequence, there are a few construction features I'd like to talk about. I built up the cowl by carving a piece of white foam to shape, then painting it with a water-based Latex before applying the glass and resin. I then hogged out the foam and washed the cowl with gasoline - outside in the open air, of course!

The motor mount/tank box is designed to allow adjustment of over 1/2 inch to fit your favorite engine. A Semco Pitts Jr. muffler fits nicely.

I used aileron servos in each wing because it is the easiest way of having four ailerons operating in sync. This also assures that the ailerons are in positive alignment with their respective wings during every pre-flight. Having an extra servo as a backup doesn't hurt either.

The wings are almost industry-standard D-tube construction; extreme rigidity at a minimum cost in weight. Rib spacing is scale and their shape is fully symmetrical like a Skybolt or a Pitts. Wire landing gear is shown because I couldn't find a suitable bent aluminum one. The fairings are easy to build for scale points, but can be left off for sprt flying. The peculiar cabane attachment results in perfectly aligned wings at all times..."

* 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.
