About this Plan
Baby. Simple glider model. 60cm wingspan.
Christian Husvik very kindly sent in some notes on this model:
Quote: "Hi Steve, Thank you for this excellent site. I had a glider very similar to this when I was young. It was a Swedish kit called 'Sparven' (means 'the Sparrow'). I have attached a photo of the drawing [see more pics 005] as a reference. This inspired some Googling, and I found another picture of a Baby here: http://jerrysoderberg.se/model%20linkon%20frifl.html [see more pics 004].
The 'Baby' was apparently designed in 1948, and was kitted and sold by Dansk Modelfly Industri. The building instructions don't say much about the materials being used except for the two fuselage stringers (3x5 mm spruce), but but based on what was used in 'Sparven' and what was typical for Scandinavian models at the time, I would guess:
Forward fuselage piece: 3 mm plywood. Wing ribs: 1 mm spruce or plywood (if you would like to build one, 1.5 mm is probably easier to cut and cheaper to obtain). Tail feathers and 'wing ears': 1.5 mm medium balsa. Main spar and leading edge: 3x5 mm spruce. Trailing edge: 2x10 mm spruce or hard balsa.
The wing is covered on top only. It is to be covered before the 'wing ears' are glued in place. Cut the tissue about half a cm outside the wing tips to a sawtooth pattern. Attach these to the outside rib before attaching the 'wing ears'."

Did we get something wrong with these details about this plan (especially the datafile)?
That happens sometimes. You can help us fix it.

* 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.
