About this Plan
Zaunkonig. Free flight scale model German primary trainer.
Quote: "A 39 inch span Flying Scale Model. Zaunkönig, by John Greenland.
WHEN John Greenland first flew his prototype at Eaton Bray, the manner in which this deep blue parasol lightweight dragged its high-cocked tailplane around flat turns, drew sighs of appreciation from our scale-loving colleagues. For, not only is this job built to perfect scale, and realistic in all views, but it also flies exactly as does its full-scale counterpart. You'll notice in the reduced scale plan that scale extends even to the airscrew in this unusual free-flighter. Note too, how the designer has made the wings detach in the proper manner to facilitate transportation - and also that undercarriage which will take the hardest of knocks, yet spring back into place ready for another test flight.
Accuracy of this model is assured, for every line has been scaled exactly from the original German student drawings - now happily in the hands of the Ultra Light Aircraft Association. The full-size job, a very much 'one-off' aeroplane, is more fully described elsewhere in this issue and, you will notice, is the subject of our cover paniting this month.
If you want to build one of these unusual but fascinating scale Zaunkoenig models. full-size drawings for the 39-1/4 in replica, complete with a reprint of the cut-away drawing and full instructions on building by designer Greenland, are available frorn APS, price 5/- post free.
Designed around the Amco .87 diesel, the model was also tried with one of the new type 1.5 cc diesels which proved to be too powerful. Top limit should be around the 1 cc mark in diesels, and up to 1.5 cu in Glow plug motors. With the Amco, and an 8 x 5 in prop, a shallow climb to the left, with an equally shallow glide was the trim of the prototype."
Quote: "Time to contribute one to the growing historical stash! 39.25in span scale FF for 1cc glow/diesel. 1/8 scale. Designer is John Greenland, published in Aero Modeller. I have never seen any other plans for this particular aircraft. The prototypes apparently had pretty impressive STOL capabilities."

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 (oz5349) 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/Braunschweig_LF-1_Zaunk?nig
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.
