About this Plan

Curtiss SOC-1 Navy Scout. Rubber scale model biplane.

Quote: "How You Can Create a Model of a Curtiss Navy Scout That Flies With Great Precision.

THE Curtiss SOC-1 is the latest scout-observation machine built by Curtiss for the navy. As such, it is designed to meet the strenuous requirements of operation from battleships and cruisers. The ship is already noted for its ruggedness of structure and versatility of performance. Prominent among its many praiseworthy features are the low landing speed, excellent handling qualities and the inherent safety for the crew.

The SOC-1 is pleasing to the eye both from the standpoint of appearance and proportions. For that reason it makes an interesting model to build and fly. Because of the fine design of the large ship, you will find that the model will fly as readily as a duck takes to water.

The constructional methods with one exception are conventional in our model. The fuselage is constructed by assembling the bulkheads on four master stringers already cut from sheet balsa. By adhering to this practice, all chance of error is eliminated.

Fuselage: Trace the side outline of the fuselage on a piece of 3/32 sheet balsa and cut two master stringers to the depth shown in black on the top view of the fuselage. The top and bottom master stringers are cut from sheet in the same manner. Mark on all the master stringers the positions of the bulkheads. Cut the bulkheads as shown from 1/16 sheet. Cut only the notches for the master stringers marking the positions of the auxiliary ones until needed.

Cement bulkheads No. 2 and No. 6 in place on the side master stringers. When dry, locate the remaining bulkheads. Cement the top and bottom master stringers in place. Cement the 1/16 sq auxiliary stringers in place, cutting the notches already marked as the work progresses. The cockpit overhang is 1/32 sheet balsa. The lower portion of the body between the No.3 and No.4 bulkheads is also covered with 1/32 sheet to provide a support for the fillet block. The rudder post is a piece of 1/8 x 1/4. Bend the rear rubber hook to shape from .028 wire and attach. Reinforce the auxiliary stringers that support the center section struts with pieces of 1/16 sheet.

The cockpit formers are cut to shape from 1/32 sheet balsa. The largest marked O and shown on the plan is typical of their shape. Each one progressing rearward is smaller than the one immediately in front. As seen on the plan they are laminated when called for.

The fillet ribs are similar to the first ribs of the lower wing panels and are cemented to the bulkhead extensions forming an integral part of the fuselage. Before covering, cement the tail wheel axle in position.

To cover use narrow strips of tissue to avoid wrinkles. Spray with water and dope. Leave an opening at the bottom to install the landing gear mount.

Use strips of cellophane of a width determined by the size of each space between cockpit formers to cover the enclosure. The shape of the front of the enclosure is easily determined from the top and side views of the fuselage. The sight is a piece of rounded 1/8 stock..."

Update 14/10/2022: Replaced this plan with a clearer copy, thanks to dfritzke. This version has been redrawn on a single sheet for easier viewing, quote: "Traced by Dick Gleason, 3-84".

    ScaleType: This (oz1174) 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_SOC_Seagull
    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.
