About this Plan

Curtiss P-37. Rubber scale model fighter.

Quote: "Building the Curtiss P-37, by Paul Lindberg Model Editor and Model designer for Popular Aviation.

NOW to give you 'rubber-powered' fans a break, we feature this trim little fighter now being tested for the Army Air Corps. It is the last word in streamline designs and its performance will thrill you beyond words.

Construction of Fuselage: Main longerons of the body are constructed from 1/16 square balsa. These are placed on the plan with a sheet of wax paper between it to keep framework from adhering to plan when the cement has been applied. After the two sides have been built remove and place in an upright position on top view of plan. The cross members are now cemented into position to form a rectangular shape.

From 1/32 inch sheet balsa, cut the formers to outline shape arid cement in their respective positions. The nose block is now shaped and cemented to front of rectangular fuselage, so that the stringers may be applied. The position of the stringers is clearly shown. Although we advise you to check from front to roar in applying these so that you might secure the proper alignment. Stiff paper is used to form the cockpit.

Construction of Wings: Construct these upon a flat surface in very much the same manner as the fuselage sides. Carefully cut all ribs to the proper shape from 1/16 inch balsa sheets. Notch these carefully and cement over main spar. The leading and trailing edges are next cut and sanded to shape. Cement these carefully to the ribs. The wing panels may be built with or without the ailerons. We recommend movable ailerons with aluminum hinges as they form an excellent means for controlling the model.

Construction of Elevator and Rudder: These are constructed from 1/16 inch square and 1/16 inch sheet balsa for the rounded tips. The elevator is constructed in two separate units and attached to either side of the fuselage with individual struts on the underside of each for supports.

Construction of Landing Gear: The landing gear struts with their intermediate parts are built up from a strong grade of balsa. A little patience is required here in order to secure the proper shape. Do not cement these struts in position until wing panels have been covered.

Covering the Model: Do not attempt to cover the body with too large a piece of tissue as this will only cause a poorly covered model. For best results, cover in long strips from stringer to stringer. This method requires a little more time but your efforts will be well repaid in the end.

The wings are more easily covered. Cover the top sides first and repeat this procedure for the bottom side. After all parts have been covered, apply a light coat of water over the entire surface which will cause the tissue to shrink. A small insect sprayer is an ideal method of applying the water. Pin elevator and wings upon a flat surface so as to prevent any warping. The clear dopes are now applied two to three coats are sufficient.

Finish coating is not simply for appearance, for a full doping and a taut tight skin also is essential to high speed and efficiency."

This seems to be the inspiration for Stanzel's Shark (oz302) series designs. Do you think, Steve?

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.
