Baby (oz4545)

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'."
