About this Plan

Curtiss P-40. Rubber scale model. A Whitman 'Exact Scale Flying Model'.

Planfile includes detailed build instructions.

Quote: "Study plans, perspective sketches and instructions carefully and thoroughly before attempting model construction. Time and patience are required to make this exact scale model. Always bear this in mind. The following few additional tools and materials, other than those supplied, are necessary to build this airplane model: A razor blade (preferably one with a heavy rounded back); a small board upon which to work and cement parts; about fifty small thin pins; a pair of pliers for bending shaft; some small pieces of sandpaper; and a piece of waxed paper 12 x 36 inches.

STEP 1. SANDPAPERING Material: Wood Block and Sandpaper (not furnished). For sandpapering obtain a small block of wood and fold sandpaper tightly around it. Rub sandpaper covered block with an outward motion LIGHTLY and SQUARELY on all balsa strips. Avoid rounding edges of square longitudinal pieces.

STEP 2. SPARS, ETC. Material: Sanded Balsa Strips. From the sanded strips select the correct sizes as required on the plan for leading edge, spar and trailing edge. Do this before any notches are cut in ribs so that fit will be very close or tight. A good close or tight fit requires less cement. Consequently, less weight will be added to the finished model.

STEP 3. WING - RIBS - WING TIPS. Material: Printed Balsa Rib Sheet. With a razor blade cut out illustrated ribs and wing tips from rib sheet as they are needed in the process of building the wing. This will prevent pieces from being lost. Begin assembly by working over the wing in the top view. It is advisable to place a piece of waxed paper over plan to prevent wood parts from adhering to and tearing or soiling plan when they are removed. While working over plan hold down balsa parts with small thin pins.

The wings are assembled in two units, namely, right and left panels. Place spars and trailing edges in position and insert ribs beginning with A, B, C, etc. After all ribs are in place, fit leading edges in position and complete wings by inserting all curved pieces. Cement all joints carefully and when they are thoroughly dry remove wings from plan.

STEP 4 • ELEVATORS AND STABILIZER Material: Balsa 3/32 sq, 3/32 x 1/8 and Printed Rib Sheet. The tail is assembled in two units, namely, stabilizer and elevator. Sandpaper all strips as explained in Step 1, before cutting, to required lengths. Use waxed paper and pins in assembly. Cut cross members and cross braces to required sizes and cut curved tips from rib sheet. First, place cross members and then front and rear edges in position. Pin down firmly. Apply small amount of cement to cross braces and curved pieces before inserting and pinning down into position. When all pieces are in their proper places, allow cement to dry thoroughly before removing from plan. Two black strips are printed on rear of plan. These are to be used for paper hinges. Cut off hinges to required sizes and slit balsa cross members at positions indicated and insert hinges. Apply cement only to outer edges of hinges..."

Update 28/10/2020: Replaced this plan with a (much) clearer copy, also printwood and decals, thanks to MikeKelly.

    ScaleType: This (oz7363) is a scale plan. Where possible we link scale plans to Wikipedia, using a text string called ScaleType.

    If we got this right, you now have a couple of direct links (above) to 1. see the Wikipedia page, and 2. search Oz for more plans of this type. If we didn't, then see below.

    ScaleType is formed from the last part of the Wikipedia page address, which here is
    Wikipedia page addresses may well change over time.
    For more obscure types, there currently will be no Wiki page found. We tag these cases as ScaleType = NotFound. These will change over time.
    Corrections? Use the correction form to tell us the new/better ScaleType link we should be using. Thanks.

This is a great scan, thanks to Mike, and the detail is really clear now compared to the previous version. I'm a great fan of the early P-40. Sometimes I can't resist a plan, so I have spent an hour fixing very minor issues on this one, removing the paper creases and doing a mini cleanup.

* 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.
