Cessna L-19 Bird Dog (oz2516)
About this Plan
Cessna L-19 Bird Dog. Kochmans 29in span all-sheet balsa model for either FF or CL, from AT Oct 1952.
Quote: "Cessna L-19 Bird Dog. Has The Half-A flying scale bug gotcha? Then what better project could you try than this beauty?
During the fall of 1949, the Air Force and the Army worked out a set of specifications for a new and improved liaison airplane. Several leading aircraft manufacturers entered into competition to design an airplane that Would fulfill these specifications; the Cessna 305 was the winner.
Deliveries of this model in quantity were made in the fall of 1950 with the Army designating it their L-19. On duty in combat areas six to ten hours every day, this flexible observer has proved itself tops for 'flushing' enemy troops, hence the nickname Bird Dog.
The Bird Dog is an all-metal airplane with a 36 ft wingspan and is powered by a 213 hp engine. It has a maximum speed of 146 mph and an observation speed of only 46 mph.
The model presented herewith is scaled one inch to the foot directly from factory-supplied drawings. However, in order to improve lateral stability and all-around performance, the dihedral angle and stabilizer area have been slightly increased. Control line scale fans should follow the scale stab and dihedral - as per dotted lines on plan.
In keeping with the all-metal construction of the Bird Dog, our model is constructed primarily of 1/16 in sheet balsa. Light weight being a prime requisite of any successful Half-A flying scale model has more or less dictated that the finished model be patterned after the National Guard's polished aluminum finish with dark green anti-glare panels. The olive drab paint job as used by the Army and the Marines would require considerably more applications of colored dope, and therefore add weight, to achieve the same finishing results as can be had with two or three coats of aluminum dope.
Start construction of the fuselage by cutting the sides and formers to shape. Notice that former F-3 is built up and includes the plywood landing gear mount which should be drilled for the 'J' bolts before assembly is begun. Mark the former locations on the inside of both side pieces and cement the side doubler sheets to the sides between F-1 and F-3. Assemble the sides by first cementing F-3 and F-4 in place..."

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.
