About this Plan

Heinkel He-100D. Scale rubber model. A contest-winnning design - winner of the 1977 Nats.

Quote: "Heinkel 10 BY DON SRULL Exciting rubber-powered Free Flight Scale model of a little-known World War II German fighter that offers competition-type performance for the contest flier, fun and games for the sport builder.

For many years, I had wanted to build a rubber-powered model of the Heinkel 100D. The airplane has a fascinating and somewhat mysterious history, but more important, I have always liked its sleek and graceful lines. Last, but not least, its very long nose moment, the tall and wide-track landing gear, adequate tail surfaces, and clean lines make it an almost perfect subject for rubber-powered scale. While low-wing models are a little more touchy to adjust than the more conventional high-wing cabin or parasol types, these problems have been exaggerated to the point that most people have been reluctant to try the countless and beautiful low-wingers that are just waiting to be modeled.

Clarence Mather has helped prove how competitive such models can be, with his winning, well-known Stormovic (oz1416) and PT-19 scale ships.

Until fairly recently, very little usable information was available on the Heinkel 100 series of aircraft. Worse yet, the little data that was available, shortly after the war, was both conflicting and inconsistent, so the He100D was kept in my 'models to be built someday' file.

In the last few years, however, an enormous amount of good reference information has been published on German aviation and aircraft. The He 100D is covered very well in both William Green's book Warplanes of the Third Reich, and in the Aero Publisher's booklet The Heinkel 100, 112. The latter publication has a wealth of photos, and a full color three-view of a particular HE 100D in full battle finish, including phony squadron markings (more about this later). I selected this aircraft to model in three-quarter scale, which gives a span of about 23 inches. The only appreciable deviation from scale in the model is an increase in dihedral.

By selecting and using light wood and keeping the finish to a minimum, the original model weighed in at about 1-1/4 oz without the rubber motor. At this weight, it proved to be a fine and consistent flier. An experienced builder could easily reduce the weight to 1 oz, and the flight performance potential would be increased significantly.

Although I intended the Heinkel 100D primarily for outdoor flying, I pressed it into service as my indoor scale entry at the 1977 Nats..."

Update 14/06/2017: As well as being produced by Flyline Models, this design was also published in MAN May 1978. We've added this article, thanks to RFJ.

    ScaleType: This (oz1685) is a scale plan. Where possible we link scale plans to Wikipedia, using a text string called ScaleType.

    If we got this right, you now have a couple of direct links (above) to 1. see the Wikipedia page, and 2. search Oz for more plans of this type. If we didn't, then see below.

    ScaleType is formed from the last part of the Wikipedia page address, which here is https://en.wikipedia.org/wiki/Heinkel_He_100
    Wikipedia page addresses may well change over time.
    For more obscure types, there currently will be no Wiki page found. We tag these cases as ScaleType = NotFound. These will change over time.
    Corrections? Use the correction form to tell us the new/better ScaleType link we should be using. Thanks.

* 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.
