XS-1 Submarine Scout (oz1693)
About this Plan
Submarine Scout. US Navy XS-1. Scale rubber biplane model.
This is a Golden Age Reproductions reprint of the original plan from from Model Airplane News, August 1933.
Quote: "How to Build the Submarine Scout. Complete Instructions and Plans For You to Create a Flying Scale Model of the US Navy XS-1. By John P Tyskewicz.
IT HAS long been the dream of the airplane designer to create a super but miniature craft so compact in form that it could be housed readily aboard a submarine. This rather formidable task was undertaken by expert Navy designers, with the resulting production of the extremely small US Navy XS-1. This was the first of what may prove to be a deadly weapon in warfare.
It is a small biplane of approximately eighteen feet span which can be carried in knockdown form within a cylinder that is carried upon the afterdeck of a submarine. This little ship, built by the D Martin and Cox Klemin Companies, can be assembled in a very few minutes. The power is supplied by a Wright 'Gale' 60 hp engine. Pontoons were used but the undercarriage was interchangeable so that the ship could be equipped with wheels when required.
This type of airplane lands itself readily to the construction of an excellent flying scale model. After having built and flown a model of this type, the author was well rewarded by its performance.
If you follow these instructions carefully, you should be able to build one of the finest flying scale models that you have ever seen.
Before constructing the model, the reader should understand that in order to get the performance of which this model is capable, he should make it reasonably light. The model shown in the photographs weighs .63 oz minus the rubber motor. All the balsa used is of medium weight grade. If other wood is used, vary the sectional dimensions accordingly.
Fuselage: From a 1/16 sheet slice out 7 or 8 1/16 square lengths. Drawings No.2 and No.3 giving the side view, are used by laying two pieces together for the top pair of longerons and two for the bottom pair. By spreading the drawing over a board and using pins or brads the longerons are bent and held in shape. Do not bend by heat or steam, it is unnecessary.
The inside braces are then cut and inserted by pairs. When completed and dry, separate the sides and cement in the top and bottom braces, beginning from the front. The turtle-back formers, plate No.5 are cut from 1/32 balsa sheet as shown. After assembly, the other two notches and stringers, 1/16 x 1/32 are added. Notching after assembly insures a lined-up job. The cowling, plates No.2 and No.4, is made up of two separate pieces with the seam or joint lengthwise..."

* 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.
