About this Plan

Fairchild Argus. Scale free flight model, for rubber power.

Quote: "Fairchild Argus, by EJ Riding.

THE high-wing design of the Fairchild Argus lends itself rather well to the scale flying model builder. Intended as a 'follow-on' type to the little ABC Robin (oz6835) which I described in the July 1948, issue of the Aeromodeller, the 1/12th scale 24 W.41a Argus shown here should provide no difficulty to the average scale enthusiast.

The working drawing, a 1/4 scale reproduction of which appears on the accompanying pages, together with the Bagley cut-away drawing (Page 652) fully explains the method of construction and it is only necessary to explain one or two points which might give rise to queries of a technical nature.

The undercarriage is built in two identical halves, each being pivoted at the bottom longerons. The upper strut ends in a loop, through which is threaded a stout rubber band which in turn passes through a paper or celluloid tube glued and bound to the top longerons. This provides all the spring that will be found necessary to absorb normal landing shocks.

The interplane struts, as in the Robin, are glued to the wing spars at one end and fit into brass sockets on the undercarriage at the other end. A hardwood peg at the lower end provides anchorage for the rubber band which ensures that both struts are retained in their sockets.

The tailplane and rudder are glued together as a unit and arc held in position on the fuselage by means of two bamboo pegs at the leading edge of the tailplane and a rubber band passing underneath the fuselage..."

    ScaleType: This (oz4165) 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/Fairchild_24
    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.

User comments

This is a really good plan and converts to electric power without too much trouble. If built light it will fly on a KP02 motor but a small outrunner is better. The written instruction say it came out to just over 7 ounces but mine was a bit heavier than that. Nice model though

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.
