About this Plan

Curtiss P-40. Rubber scale American fighter plane model.

Quote: "Tops in flying scale models is a design by Gough. His rendition of the P-40 fulfills NAA weight rules and flew 45 seconds.

As designs go, the new sleek Curtiss P-40 is tops in streamlining. Its power unit consists of an Allison motor of 1,090 hp. Specifications: Wing span, 37 ft 3 in; length, 31 ft 8 in. Rumor has it that this new pursuit's speed is 400 miles per hour.

Our model retains the streamlines and attractive appearance of the original and a great effort has been made to simplify the construction procedure as much as possible for accuracy and flyability. The original model consistently flew 45 seconds, which is excellent considering the fact that it has been designed according to the NAA weight ruling of three ounces per 100 square inches of wing area.

Construction. The fuselage is built in half shells. One shell is composed of the top and lower main keels, formers, nose piece and stringers. The rudder is built directly on the side-view plan of the fuselage for accuracy. Remove the fuselage half and cement the identical formers, etc to the other side. Fill in the nose between the stringers with 1/16 soft balsa. The complete fuselage is constructed of 1/16 sheet, strips, medium and hard as noted on the plans.

For the nose piece, select two blocks of soft balsa 1/4 x 1-1/2 x 2-5/8 inches and cement them lightly together. Using cardboard templates, cut to required nose shape. Now slit the block at the cement joint and hollow each half out to a thickness of 1/8 in. The radiator is built in the same way.

When the fuselage is completed, sand it smooth and cover the cockpit with thin celluloid. Cement the two 1/16" hard balsa plates in place at Section A-7; 3/32" holes are drilled in them to hold the aluminum rubber tube.

We come to the wing. Pin and cement the leading edge, trailing edge and tips together on the plan. Raise the leading edge up about 3/32 in and glue the bottom ribs in. Using a template, cut sixteen 1/16 in square top ribs. Glue the front tip of each in its place on the leading edge and trim and cement at the rear. Cut two landing-gear ribs and notch spar holes in them. Slide the two center spars in, one wing-half at a time..."

    ScaleType: This (oz5738) 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.


    Notes:
    ScaleType is formed from the last part of the Wikipedia page address, which here is https://en.wikipedia.org/wiki/Curtiss_P-40_Warhawk
    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.

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.
