About this Plan
Tubby. A 20 inch wingspan FF sport for Cox 010, designed by Colin Read.
Quote: "An easy to build, tough little 20in wingspan 'small field' sportster for the Cox .010.
FOLLOWING the publication of our feature 'Pocket Size Power Models' in the August issue, we have been plagued by requests for a simple-to-build sports job for the Cox Tee Dee .010. Colin Read has produced just such a model and we are sure that this attractive little 20 in span biplane will prove an extremely popular design.
The basic fuselage is constructed from 1/8 in sq balsa. The two sides are built flat on the drawing, building in the 1/8 in sheet pieces 'F' and the rear reinforcement. Bind and cement the undercarriage to former F2 and assemble the two fuselage sides, adding the top and bottom1/8 in sq cabin cross braces. Cement the rear of the fuselage sides together, then add the remaining cross braces and formers F2a and 3. Finally, fix the nose former F1 and then cover the top of the fuselage in front of the cabin and the nose underside with 1/16 in sheet.
Cut the cowl sides, etc from 1/4 in soft sheet, and cement firmly into position, being careful to allow sufficient room for the spring starter. Shape the cowl fairings from soft block and hollow out before cementing in place. Make the top portion of the cowl removable for engine access.
Sand the fuselage smooth and add 1/16 in dowels where shown. Cover with lightweight Modelspan and finally add the windscreen from thin acetate sheet. Give at least three coats of clear dope and one coat of fuel proofer to the fuselage, to protect the covering against the destructive glow fuel exhaust.
The wings are built directly over the plan and the construction is quite straightforward, but be careful to use hard balsa for the leading edges and spars, to prevent warping when doped..."

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.
