About this Plan

Boeing XP-940. Rubber scale model 1930s prototype fighter.

Update 03/12/2019: Added article, thanks to GTHunter.

Quote: "The Boeing XP-940 was developed for the US Army Air Corps as a single seated pursuit fighter. All data in regard to speed and so forth is kept a secret by the Army Air Corps. You will find the model to be a very speedy flyer. Then, if a great deal of time is spent in applying the details and so forth to the model you will be repaid with a very attractive display model.

COLOR SCHEME: Entire fuselage army blue with necessary striping. Wing and tail surfaces, army yellow details in black and silver, other color notes are indicated on the plan.

CONSTRUCTION OF FUSELAGE: It is necessary to place a sheet of ordinary wax paper over the plan to prevent cement from sticking to it. In building the fuselage, construct one side at a time. The longerons, vertical and diagonal braces, etc, are held in place until securely cemented, by inserting straight pins on either side of strips.

After the two fuselage sides are completed, they are pinned to top view of the plan in such a manner that the top longerons face down and the sides are at right angles with the table. The cross-members are now cemented in place, forming a rectangular fuselage. Cut formers from 1/16 inch sheet balsa and cement in their respective positions as shown on plan.

Balsa nose plate is built up from 1/8 inch sheet balsa. Stiff paper is required between nose plate and formers.

The cylinders are carved and sanded from balsa blocks. When nine cylinders have been formed, wind heavy thread around them to represent fins. Make crankcase from two pieces of balsa. Rocker arm housings, push rods and other small details of motor are made of balsa.

CONSTRUCTION OF WINGS: Cut all ribs from 1/16 inch balsa. Pin the spar in position on the plan. Now cement ribs in their proper locations. The leading and trailing edges are cut and sanded to shape and cemented to the ribs.

The panels carry movable ailerons which are a great help in controlling the flights. Make wing tips from 1/16 inch thick balsa. We highly approve of this type of wing tip, because it is much easier to construct and neater in appearance.

CONSTRUCTION OF ELEVATOR AND RUDDER: These are built from 1/16 inch square and flat balsa, and are constructed on the plan. Their construction is very simple: therefore no difficulty should be encountered here.

CONSTRUCTION OF LANDING GEAR: Study plan carefully to clearly understand the construction of landing gear. The method in which the landing gear struts are attached to the wings is plainly described.

COVERING THE MODEL: Apply tissue to the various framework members, using a light grade model airplane dope to fasten it to the outer edges."

    ScaleType: This (oz4361) 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/Boeing_P-29
    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.
