About this Plan

Monocoupe 90. Free flight scale model for rubber power.

Quote: "The Monocoupe Takes the Air. How You Can Build a Flying Scale Model of One of the Fastest and Most Popular Cabin Sport Planes. By Howard McEntee.

THE Monocoupe is a trim little ship which is much used for sport flying. It is not a light plane by any means but it is small and economical, which accounts for its great popularity. When fitted with streamlining, as our model is, and a motor of around 125 hp, the top speed is about 145 mph, while the climb is 1200 feet per minute. The Monocoupe has won many races because of its fine performance and so is a favorite with sportsmen.

The wing span of the large ship is 32 feet, which we have reduced to about 21 inches. Many different engines have been used in the Monocoupe, including Lambert, Warner Scarab, and Kinner 135, which later we will reproduce.

The seating arrangement is side by side, and two people can be accommodated.

Fuselage: The fuselage is not unusual in construction. The two sides are first built up on a board and then fastened gether. The last side to built up is not cut off the board but assembly is started right there. Since the fuselage is of uniform . width under the center section, we can start assembly with all cross struts at this point. The bulkhead A is also of this width, so glue it to the side on the board first. Then glue on the two cross pieces, top and bottom, at the rear of the cabin.

When the glue has set a bit, fasten the other fuselage side on top, holding it in place with weights. You now have the fuselage on its side, on the board. When this much is dry, cut it off with a razor blade and install the cross pieces at the rear of the cabin, two at a time, until all six are in place. You must note carefully the distinctive shape of the fuselage at the rear of the wing and take care that you have it correct, or your model will not look like a true Monocoupe.

The rudder post B of bamboo. the tail skid. also of bamboo, and the small bulkhead C of balsa are installed and complete the of the fuselage. The nose block D is of balsa and is slightly oval at the rear, the longest dimension being from top to bottom. It is easily cut out of balsa, starting from a disc of balsa..."

    ScaleType: This (oz14126) 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.

Monocoupe 90. The 90 must refer to the age of the plan. Accurate looks, but not much room left for additional lightness :)

* 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.
