About this Plan

Alexander D-2 Flyabout. Free flight scale rubber model.

Quote: "Build this flying scale model which has the proportions to make it a real performer .

HERE is a well designed pre-war American lightplane that lends itself admirably to model building. It was in the same category as the 40 hp Piper Cub, being of the same general dimensions and performance. The Flyabout had ample room for two people and a puppy - so stated Aircraft Mechanics, the manufacturer. Two powerplants were available: the Continental A40 of 38 hp, and the Szekely of 45 hp, as reproduced on this model.

The scale of the model is 1/20 full size. All balsa used should be of firm texture unless otherwise specified.

Fuselage. Begin by making the two side frames (shaded on drawing). Use 1/16 sq and 1/16 x 3/32for these. 1/16 x 1/8 stock is required for front portion of the lower longerons. Assemble the two frames in the usual way, first installing the cross-braces under the wing position. Notice that a few of the upper crossbraces, of 1/8 sq. balsa (between nose and rear of cabin), are set low to allow passage of the rubber motor.

When the fuselage frame is completed to this point, cut out the required formers from 1/32 sheet balsa. Cement each in their re-spective positions. The 1/32 x 1/16 stringers should now be put in the nose as well as the single stringer which runs along the cen-ter on the bottom. Cover these areas with 1/64 sheet balsa, using three separate pieces in covering the bottom as shown.

After cutting the rear rubber hook bulkhead to shape, bend the rear rubber motor hook from No. 15 piano wire and insert in the bulkhead, following with the placing of the unit in the fuselage frame at rear as shown. The nose block, of medium-hard balsa, is made next..."

Thanks to Pit for more detail on this plan, quote: - "from Model Airplane News April 1947. From ELBERT J. (JOE) WEATHERS (1920-1984) Alexander Aircraft Company, succeded in Aircraft Mechanics, Inc. This model is known as Alexander D-2 Flyabout with 3 cyl. Szekely engine."

Did we get something wrong with these details about this plan (especially the datafile)? That happens sometimes. You can help us fix it.

    ScaleType: This (oz1505) 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.

    ScaleType is formed from the last part of the Wikipedia page address, which here is
    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.

I think this is a Welch Flyabout, not a Porterfield. I can get more info if you want, when I return home in a week.

* 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.
