Aeronca C-3 (oz4686)
About this Plan
Aeronca C-3. Control line scale model.
Quote: "SHE was known as the 'Flying Bathtub'n the old days. Yet today there are still a few putt-putting around the country after more than fifteen years' service.
The original C-3's were built in 1933 and our model is a faithful replica even to the dummy cylinder, exhaust manifold and all the flying wires. When compar-ing flying performances, however, the real ship isn't in the same class because the model executes consecutive outside loops and vertical eights as smoothly as any stunt ship. Inverted flight is a snap regardless of the high wing and dihedral.
Some of the free-flight boys say it's a crime to put lines on such a natural free-flight scale model. They have a point, for one could search a long while for a better-proportioned scale job capable of stable flight without lines. For those wishing to make a free-flighter of the Aeronca I would recommend substituting a .19 displ motor, building up the tail surfaces and changing the wing section shown to a Clark Y.
The construction is standard throughout most of the ship making for an easily-built model. Cut formers 2, 3; 4 & 5 from 1/8 sheet and assemble on to the 1/8 x 1/4 longerons, making sure they are slanted cor-rectly according to the side view. Now cement the %2" sheet sides to these formers. Cut former #1 from a piece of 1/8 plywood. The motor mounts are gluyed solidly to this former and allowed to dry... "

* 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.
