About this Plan

Ercoupe. Free flight scale model from MAN 1943, design by Sydney Struhl.

Quote: "An Ercoupe from Lilliput. A stable low-wing scale sport plane with unusual flying ability that is easy to build. By Sydney Struhl.

JUST prior to the United States' entry into this second World War the light-plane activities in this country was on a terrific upswing. Second-hand planes sold as cheaply as autos and plane manufacturers were offering flight instructions with every new ship purchased. Things were boomin'. Then along came the war and with it all the necessary restrictions and regulations needed for our defense. Aircraft manufacturing turned its full attention to getting the best equipment out to get this war over as soon as possible. And that is as it should be.

All this adds up to the stalemating of lightplane activities for the duration, but with the promise of great advancement after the war.

One of the newest and finest lightplanes to be produced is the Ercoupe. The Ercoupe is a two place airplane ideally suited for transportation or training. ()f the $2,000 class, the Ercoupe looks more like a snappy military pursuit job than a sportplane. Unusual points of interest in the ship is the tricycle landing gear, twin rudders and practically all metal construction.

Perhaps the most important feature of the Ercoupe is its ease of handling and performing. The Ercoupe is certified by the Civil Aeronautics Authority as 'characteristically incapable of spinning.' And the ship does have amazing stability - it will not get out of control. Even with the wheel full back, straight flight can be maintained or turns performed at will. It is absolutely impossible to spin the ship. The quick takeoff run, fast climb and high sustained cruising speed of the Ercoupe provides point-to-point transportation which will surprise and please the private pilot. On the ground as in the air, the plane handles with great ease; no nose-overs are possible even with full application of the hydraulic brakes.

The Ercoupe's structure is all metal, is the covering of all but the outer wing panels. The use of corrosion-resistant aluminum alloys in structure and covering brings to the lightplane pilot the dependability and freedom from maintenance of the large transport planes.

Powered with the Continental A-65 engine, the plane has remarkable performance with surprising economy. Maximum speed is 117 mph and cruising speed is 105 mph. Cruising range is 350 miles and the landing run is only 200 feet. Fuel consumption is but 4 gal per hour.

As a scale gas model we claim that the Ercoupe performs just as well as any other model even thought it is a low-wing design. You know that a low-wing model can be designed to fly just as well as any parasol model if certain aerodynamic principles are observed; such as proper distribution of your forces (CG, CLA, CP) and the correct setting of attack of the plane and thrust line..."

    ScaleType: This (oz1045) 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.

* 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.
