About this Plan

Das Ugly Stick - Classic radio control sport model. This is the Ugly Stik as it first appeared in Grid Leaks magazine, May/June 1966.

Quote: "There are at least three versions of these plans. The first one I saw was when John Pond still had his plans service, and Phil Kraft drew a special edition for him, now available through AMA plans service. That version has the initial design of no dihedral or false ribs but included the built-up, sheeted tail surfaces. The Jensen kit version was changed a little for producing the kit of that name. That version has noticeable dihedral, false ribs at the leading edge and a solid sheet tail assembly. The version I sent you here is a copy of the original drawings as sold by the 'Grid Leaks' magazine and has no dihedral, no false ribs, but with the built-up and sheeted tail assembly ...The pictured airplane I built was from the Pond plans. For interested modelers, a US company named LazerWorks has a laser-cut kit that will neatly work with any of those three drawing versions. My example is per print except I used a K&B .45 Sportster instead of the VECO .45 called out on the plans, was covered in Coverite and Fabrikote, with Sig butyrate dope, instead of silk. A great flying airplane. I was told by Danny Lutz, who worked at Kraft Systems for quite a while, that Phil would usually use an Enya .60TV for power. If you use color on the thumbnails on your site, there will be those who say K&B never made a Greenhead .45 Sportster and they would be correct. I painted it as a fake VECO :)..."

Quote: - "Hello at Outerzone, and thank you so much for your great website! Now I would like to contribute something, but it should be clear that I don't want to adorn myself with borrowed plumes. The offer I can make is more or less on behalf of George A. Walker, who had the idea for Das Ugly Stik as we know it and even posed with his prototype on the Grid Leaks magazine's title page ...of course, George drew the plan published in Grid Leaks as well, but he has 'only' his original vellum, not the version formatted for print. Again, you have a really good scan at Outerzone (#5175), but his one has better contrast and detail (and more file size). So you could offer it as an alternative, even if only as curiosity for those who appreciate the (autographed) original. Furthermore, George sent me a (printed) copy of the May-June 1966 Grid Leaks issue with the article about Das Ugly Stik. I scanned it in high resolution because the font is rather small, and I scanned all pages, including title page and picture pages. You have only the text pages in lesser resolution, so this would be an enhancement and a completion ...I would really like to see these files offered at Outerzone. Kindest regards,"

Hello Steve and Mary, Here's my build of the Ugly Stik based on the Grid Leaks plans [more pics 009, 010]. I didn't follow the plan exactly as I used an electro setup. The 1/4" sides are replaced with 1/8" sides for example. I also used a D-box and webbing (with 1 mm balsa!) on the wing for greater stiffness and adopted some other building techniques, including making the tailpieces lighter. The outlines however are 100% Ugly Stik. I also included 2 degrees of motor incidence, no side thrust. Electro setup is a SK3 5045-450 kv motor, on 6S 3700 mAh LiPo with a 15x8 prop and with this setup it flies like a madman :) Weight is 2626 grams. Build report in Dutch can be found here: www.modelbouwforum.nl/threads Thanks for Outerzone!

Latest project is a classic Ugly Stik, most popular model ever built, worldwide. Right now, I'm re-drawing the plans to lighten it up a bit for electric power, same size as the original, built as a low wing taildragger. As to how it got its name, when Phil Kraft showed up at the field with his first version, the guys present said, "Damn, Phil, that thing looks like it was beat with an ugly stick". The rest is history.

* 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.
