Curtiss O-52 (oz1504)
About this Plan
Curtiss O-52. Free flight rubber scale model from Dec 1941 Air Trails.
Quote: "SCALE THE CURTISS O-52 BY RONNIE ALBERT. Realism and high performance are combined to an amazing degree in this stable air corps flying model.
ONE of the latest and most talked-about US army war birds is the new Curtiss Observation - the O-52. Designed especially for 'peeking' duty, the O-52 is one of the most efficient in its class. And although few realize it, aircraft of the observation type are just as important, if not more so, than those 400 mph fighters!
This O-52 will make as beautiful and consistent a flying model as the real ship is efficient - and that's something! Having a wing area of 129 square inches and a total flying weight of 4 ounces, our O-52 is just up to weight rule - a characteristic of extreme importance in flying-scale competitions.
The construction is rather simple and no difficulty should be encountered if the directions are carefully and accurately carried out. As with most flying scale models, the fuselage is by far the most difficult unit to construct - so, before that enthusiasm is lost and you start to cool, let's get on with the construction.
With the assumption that you have already enlarged the plans to read full size or else eliminated 'model builder's torture' by sending your thin dime to Air Trails for the full-size drawings, start the construction by cutting out the bulkhead halves from 1/16 stiff medium sheet balsa. After the bulkhead halves are carefully sandpapered and labeled, cut from 3/32 medium sheet balsa the fuselage 'keel' and pin directly over the drawings. Then cement each bulkhead half in place, care being taken to make certain that all are perpendicular to the plan surface.
After the cement has sufficiently dried to permit handling without the fear of bending the bulkheads from their perpendicular position, the 3/32" square "line-up" stringer should be cemented 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.
