About this Plan

Horten Ho-IX V3/ Go 229. Scale model flying-wing, for radio control. Scale is 1/8. For power or glider versions.

Also known as the Ho 229, as it's a scale version of the "Horten H.IX, RLM designation Ho 229 (or Gotha Go 229 for extensive re-design work done by Gotha to prepare the aircraft for mass production)." See wikipedia entry.

    ScaleType: This (oz1736) 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_Ho_229
    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.

Horten IX is a seductive plane. It's also one of the most complex to model in all of modelling. Mr Bales got it 100% wrong he had no idea what he was doing with this one. Honestly suggest no one download this plan...

I tried to build from these plans and gave up. The airfoil sections are even wrong. No one that I know of has built a flying model from these plans. Wings on the web can help. Or Traplet.

Here are some photos of my Horten Ho-IX [more pics 003-007]. Reading some of the other comments, apparently either this is not scale or too difficult to build. I assure you this is not for the faint of heart. These drawings must've been from a kit that had possibly a fiberglass top and bottom plastic or something, because the center section is very vague and there's not enough ribs to plank it with balsa or so forth. So looking at a lot of photos on the internet, I got inspiration and here's the result. After initial assembly of the wing I did give it a glide test and it flew. Now trying to engineer power system with EDF Jets. I made it from dollar store foamboard mixed with some balsa pieces & spruce here and there, but this project was actually just for a test to see the feasibility if it would fly. I've read a lot of things on the internet and people were asking about this particular plan by Jack Lynn Bales. Well, a test glide on the hill was successful. However, the CG I had to place it back further than on plan.

I have more photos that you may like to post [more pics 009-011]. First photo is one of scale just to show you how big the Horten 229 is. The second one is the underside of the Horten.

I have a story about this plan. About thirty years ago I guess, the big model show out here was in Pasadena California. It was always packed with people. I had bought some stuff at the swap meet and was milling around. A guy came up behind me and my buddy and said hey whatcha got there? I chatted with him for a few seconds and he asked "do you want to buy some plans?". I wasn't interested but he was insistent and unrolled some plans for me to see. They were really nice and he was obviously so proud of them. I asked who drew them and he proudly said "I did!". Well as it turns out, he was Jack Lynn Bale. I bought this plan and another two or three and still have them. I learned he died shortly thereafter through the grapevine. I have always cherished them and maybe someday I will try to build one of them. True story.

By the way, he said that most of his later designs were intended to be scale slope gliders, not power models. The Horten in particular was a glider, not a power model. He said that guys commonly attempt to convert them, but that they were really gliders. This makes sense because I understand from others that knew him, or "Of Him", said that he was into slope soaring later in life and not so much into power models - lots of guys gave up IC models as the cost of fuel went through the roof in the '80s and slope was at least as much fun without the cost or mess. When I asked if he had heard of a successful conversion of the Horten, he looked at me as if he wanted to say yes, but instead said "Well ... a lot of guys are working on converting them - it flies great as a slope soarer though". This was 30 years or so ago thus it was before miniature systems and EDF, even I/C Ducted Fans were rare and in their infancy at that time. Slope was very popular back then, although it has all but died out now because of the electric revolution that has occurred. At any rate, I cannot stress too much how impressed I was of how proud he was of his work. They were truly art work to him.

Love this build! Is there any way it could be reduced to a size of about 48-54” range?
Chris Ingermann - 10/04/2020
To print a plan at a different size, I do it when printing. It's easy, just print in whatever percent you want. For example, a 60 percent print will yield a wingspan of 50.4 inches, right in your range. I print the plan sheet in TILES, then tape the sheets together, easier than traveling to a printer. I use Foxit Reader an alternative to Adobe without the nag screen. Be sure to check the "cut marks" box, easier to line up the sheets. Adobe Reader will also print in POSTER if you have version 10 or above.

Greetings, Like a lot of people, I’m fascinated by this aircraft, and this set of plans.
I’m particularly intrigued by the build by Larry Welle. If he’s out there I’d like to hear how it all worked out.
Mr. Welle refers to dollar store foamboard. The foamboard my dollar store sells has paper on both sides, and is 3/16” thick. Is this the same stuff? I’ve tried peeling the paper off, but it doesn’t come off cleanly, and the board seems too stiff to bend. Can anyone shine a little light on this subject?
I love OZ, and learn a lot just by studying the plans and articles. I’m retired, and money is tight, so cheap pleasures are valuable. I hope someday to contribute, both financially and plans. But right now all I can do is offer my thanks.
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.
