About this Plan

Swallow. Simple all-sheet rubber model.

Quote: "DESIGNED primarily for the purpose of testing a new type of monocoque fuselage design, the Swallow proved to be such an exceptionally fine performer that I decided to make the design available to everyone. The drawings will show you that the novel fuselage is unbelievably simple for all its good looks, and after weeks of flying, including breaking rubber motors, my Swallow still shows signs of a long future career.

Here is a chance to get out of the rut of weak frame-work paper-covered models and build a really advanced model!

Fuselage. The fuselage design is so radical that I had to work out a completely new construction procedure for it, so that even the most expert model builder will find it necessary to read the following instructions very carefully. In general, though, the most difficult part of building this fuselage can he summed up in the word 'bevels.' If you succeed in cutting the various bevels in the fuselage parts with a fair degree of accuracy, the rest of the work is very simple. The best method of making these bevels is to use a sandpaper block in conjunction with a rough angle template. Hold the member so that the edge to be beveled projects slightly over the edge of your work table, and tilting the block at the correct angle - as shown by the template - sand the edge slowly backward and forward, exerting an even pressure.

The sandpaper need not be very fine. If upon trial assembly the bevels are shown to be a little off, a correction can be made almost immediately by using the sanding block again. To assist us in talking about these bevels, I will set up the following convention. The right side of the fuselage will be understood to be on the right side of an imaginary pilot sitting in the plane. He faces forward, of course! Here are the steps to be followed:

Cut the two fuselage sides and the top out of 1/16 x 3 in medium balsa stock. To insure accuracy in this step, trace the outlines from the plans directly to the balsa, using carbon paper. Make the bulkhead C from three sections of 1/8 x 3/16 medium balsa, using plenty of cement. Laminate the tail plug B from two 1/16 hard sheet blanks. Also cut out former A, the nose former.

Bevel left fuselage panel on the bottom from its lowest point, where it meets bulkhead C, clear to the back, at an angle of about 45 degrees. Bevel right fuselage panel on the top from the end of the window to the rear of the fuselage at an angle of about 45 degrees. Bevel the top panel of the fuselage on its left side, the whole length, at an angle of about 45 degrees. Bevel bulkhead C on the top by measuring down 1/16 on the front side and cutting as shown in the plans. Also bevel each side slightly on the rear face..."

User comments

Hi, I thought you might like to see the Swallow that I have just built using the Malcom Abzug 1939 Outerzone plan [model photo & more pics 005]. A very interesting construction with its triangular fuselage and curved sheet wing. Thank you for maintaining the plan base, I already have a large list of builds waiting to be done. Cheers.

* 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.
