About this Plan
Lil Auk. Rubber driven float plane.
Quote: "Little Auk. Over land or water, John Trinder's 30 in rubber-powered design is a prim performer.
THE LITTLE AUK is the name for an almost extinct seabird and regrettably rubber-powered floatplanes also fall within the almost extinct category. It is hard to explain why this is so, for models like this one are particularly easy to build and trim, and are a great pleasure to fly. Being convertible to a landplane by removing floats and plugging in a normal wheeled ulc, it is a double purpose design and for contest work a one-bladed folding prop assembly is suggested. One further note before building - do pre-cement joints wherever possible as this at least doubles the life of any model.
Build both fuselage sides at the same time - one on top of the other. While these are setting, make up cabin frames P1 and P4. Separate sides and complete construction of box fuselage over the plan view, adding spacers. Fit 1/8 x 1/32 diagonals - these add great rigidity for little weight. Bind the nose with cotton and rub cement over strands, and secure the undercarriage tubing to appropriate spacers.
Build floats by fitting 1/16 sides on the main former, after u/c has been bound in place then add LE, TE and sheet covering.
Slot the wing and tail trailing edges 3/32 in deep to key the ribs. Pin down wing TE with 1/32 packing under front. Cement ribs to TE and add leading edge and top spars. When set, remove from board and add underspar. Raise tapered panels 2 in under outer rib and join to inner panels. Same system applies to the tailplane.
The upper and lower fins are built over plan and cemented to fuselage using appropriate holes in 3 in sheet for positioning.
Original is covered with lightweight Modelspan throughout. Watershrink and give coat of 50/50 dope and thinners to wing and tailplane and two coats to fuselage. The floats need extra coats of Banana oil for waterproofing..."

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.
