Junkers D-1 (oz2496)
About this Plan
Junkers D-1. Scale WWI fighter for radio control by Joseph Tschirgi, from American Aircraft Modeler issue 11-68.
Quote: "A WWI aircaft returns. Remarkably advanced for its time - this 1918 fighter has the configuration and proportions for a fine R/C scale model.
MOST scale modelers spend as much time leafing through old volumes of aviation publications searching for the perfect model as they do building. The perfect R/C scale subject must:
1) be a good aerody-namic configuration in its proportions.
2) have simple, yet interesting lines (a minimum of struts and other difficult-to-reproduce features).
3) have a rugged landing gear that still looks like the real thing.
4) be so obscure that all your flying buddies ask: What is it?
The last item is most important!
The Junkers D-1 comes as close to filling all these requirements as any WW I aircraft. Built during the summer of 1918, the D-1 culminated three years of single-seat fighter development by the Junkers plant in Dessau. All the prototypes (J1-J9) in this period were remarkably advanced air craft: all-metal, cantilever monoplane configuration. Originally (J1-J2), they were covered with sheet steel and earned the title 'Tin Donkey.' They were quite heavy and apparently difficult to fly.
The latter 'J' series, and the D-1 were covered with corrugated aluminum, extremely rugged, and powered with Mercedes or BMW en-gines, and had competitive performance. Structurally, they were not similar to modern skin-stressed design, since, for ex-ample, the wing was a complex steel tub-ing framework which, in modern automo-tive terminology, resembled a space frame. Here the corrugated skin only covered the wing ribs and carried no spanwise load. But, it was an exceptionally clean machine for the period.
It is an ideal modeling subject, since it combines simple, but appealing lines, with interesting scale features - such as the car-type radiator which allows a fully enclosed engine.
About 50 of the type were built. A few got into action before the end of WW I, hence some latitude is available where finish is concerned. Photographs indicate that both the 'sand and spinach' camouflage used on our model, and plain aluminum finished types, existed. Windshield, markings, cowling and gun installation details also varied between individual air-craft. (I recommend that you get a Profile No. 187.) This publication will furnish the AMA required proof-of-scale documentation.
Incidentally, both a short and long fuselage version of the D-1 existed. Our model is the long, since short nose and tail-moment arms are not happy combinations..."

Did we get something wrong with these details about this plan (especially the datafile)?
That happens sometimes. You can help us fix it.

ScaleType: This (oz2496) 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.
Notes:
ScaleType is formed from the last part of the Wikipedia page address, which here is https://en.wikipedia.org/wiki/Junkers_D.I
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.

User comments
Steve & Mary - I attach the article for Joe Tschirgi's Junkers D-1 from Nov., 1968, "American Aircraft Modeler", to accompany the plan you already have on Outerzone. I posted this on RCGroups at http://www.rcgroups.com/forums/showpost.php?p=32854048&postcount=30 I list this as 54" span while your scan says 52". All the scans I've seen (or done) for this plan have been from the unscaled magazine page, which does not include a span, so the original span is nebulous. In the article he states he sized the model to fit 4-3/8" wheels, but he also states he used a scale of 1.72"=1ft. Since the fullscale span was 29'6", a 1.72"=1' scale would give a span of 50.74", but scaling it for 4-3/8" wheels gives about a 54" span, which better fits the balsa sizes and other dimensions stated on the plan. The 52" indicated on your site is certainly a decent compromise. "You takes your pick", and I picked 54", though that doesn't matter for my article scan. Keep up the good work!DPlumpe - 07/10/2015

Notes
* 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.
Scaling
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.
