About this Plan
Schleicher K8B. Radio control scale model sailplane. Wingspan 1800 mm.
Direct submission to Outerzone.
Quote: "Hi Mary and Steve, here is a copy of a Schleicher K8b plan by Karl-Heinz Denzin from Hegi in 1961, as far as I know. Wingspan is 1800mm. Instructions in German are also included and a copy of the catalog picture from my 1965 Hegi catalog. It is on my to-do-list in the future. Cheers, Frank"
Note the instructions, written in German, include some excellent build pics showing detailed assembly, along with part numbers.
Update 5/11/2023: Added transcript of the instructions in English, thanks to Pilgrim.
Quote: "Construction instructions 'Schleicher K8B'.
General: The blueprint is drawn throughout in natural size, so that the fuselage halves, rudder, elevator and the two wing halves can be assembled directly on the blueprint. The right half of the fuselage and the left wing are assembled on the back of the blueprint, which is made transparent by painting it with oil.
For gluing, it is advisable to use a quick-drying hard glue such as UHU-HART; only the paneling of the vertical and horizontal fins as well as the upper wing paneling are glued on with a slow-drying cold glue such as UHU-COL or with contact adhesive (UHU-CONTAKT).
The individual parts are numbered throughout in the order in which they are required during construction. In order to enable assembly as quickly as possible, it is advisable to saw out the non-pre-cut plywood pieces in pairs beforehand, for which the printed ones are placed on the corresponding unprinted plywood boards and stapled together from below using thin wire pins.
Fuselage: Keel 1 and hull strap 2 are attached to the drawing with pins after strap 2 has been cut out 1.5 mm deep at the top to accommodate the planking 48. The frames 3 to 7 are then inserted into the keel and the middle section of the fuselage is completed by the tongue 8, the frames 9 and 10 and the root rib 11.
If the frames 12 to 15 are glued to the strap 2 and frame 16 and the side fin spar 17 are stapled to the drawing, the straps 18 to 23 can be used. In order to avoid tension as much as possible, the belts are either pre-bent using steam at the front or sawn along the middle of their wider side to frame 6 and glued again immediately when inserted.
Now the side fin ribs 24 to 28 are glued against spar 17 and connected at the front by the nose strip 29.
After the frame 30 has been inserted, the planking 31 to 35 is inserted or glued on after they themselves (33) or the underlying components (29, 3, 4, 30) have been beveled accordingly. The gaps between the root rib 11 and belt 21 are filled with the fillings 36 made from waste balsa and the horizontal stabilizer support between the frames 15 and 16 is glued to the belt 21..."

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 (oz13051) 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/Schleicher_K_8
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.
