    ScaleType: This (oz11324) 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/Horten_H.IV
    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.

Many thanks to Rich for pointing out this is actually a scale model.

Of course it is a scale model, but using a Jedelsky construction on a Horten design would be an acceptable motive for murder. And this being a FMT plan would make it treason too :-) At least plank the wing under surface as well! For more on the Horten Brothers and other flying wings see the old but still great website at twitt.org, it has nothing to do with a certain piece of software.

I don't think this is a Horten IV. Canopy is wrong and aspect ratio too low. I think it's probably either an XVc or XVI. More info at nurflugel.com

Maybe Miguel would be happier if it was sanded out of a nice piece of c-grain and had the washout put in by soaking and drying. This would, of course, need a lot of washout.

There are many ways to skin a cat, Mr Lincoln, and I'm afraid this wouldn't be my favourite method, I'd follow the classic ribs and spars path instead. The Horten IV was a fine glider, it's glide ratio could reach 40:1 and there are quite a few full-size replicas flying today. Even so it appears to me that this scale glider is too small at 36" to worry much about fidelity, if it flies well it will surely look well, Jedelsky or no Jedelsky.

Greetings, Somewhere out there is a Horten flying wing plan that appeared in Air Trails magazine, I think in the late ‘40s. It used a built up construction, with lots of washout and a big airfoil change across the wingspan. It generally resembles the Horten IV, though as I recall, the article admitted that the aspect ratio had been reduced. I don’t know if it was ever available as a full-size plan. I think it only appeared in the magazine in the’40s, and again in the’70s, in the Air Trails plans collections. Maybe I or someone else can find it at rclibrary.co.uk. It might be a worthwhile add, at least as a link.
Let’s be careful out there.

OK, I took my own advice, and got lucky. The design I referred to was titled “Flying Wing Glider”, and can be found in the Air Trails Annual for 1952, page 38, see https://rclibrary.co.uk/title_details.asp?ID=2132. The article refers to the Horten designs, particularly the Horten IV. Stay curious, and of course,
Let’s be careful out there.

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.
