About this Plan

Velie Monocoupe. Radio control sport-scale model.

1929 Velie Monocoupe by Colonel John A DeVreis. RC scale for .30 to .60 engines.

Quote: "The Velie Monocoupe is a slice of aeronautical nostalgia. Designed by Clayton Folkerts, of later racing aircraft fame, the Velie was the second in a long line of Monocoupes - a definitive design. Powered by the 65 horsepower Velie air-cooled radial engine, the 1928/1929 version of this famous monoplane took home more than its share of trophies in the stock plane races that were popular in the late 20's and early 30's: With a span of 32 feet and an overall length of 19 feet 9 inches, the Velie Monocoupe cruised at 85 mph. It seated two, in chummy side-by-side comfort. An excellent training aircraft, its stability also attracted the sportsman (and sportswoman) pilot of the era.

Factory drawings were used in scaling the model - twice. Basically it is a 3x enlargement of Herb Clukey's outstanding rubber-powered model Velie Monocoupe (oz405) from Flyline Models. Herb used the factory drawings in producing his 3/4in scale Monocoupe. He loaned me the same drawings to me, to assist in the deisgn of the RC version. As far as can be determined there is no deviation in scale from either effort. Outlines and wing sections are as 'Monocoupe' as one can get. The RC version includes more ribs than the prototype and the wing and landing gear struts attach differently - but these changes were dictated by the materials used in model construction. The model falls into the standoff scale category, due to these small changes as well as a lack of cockpit detail and the exposure of the engine cylinder as part of the 5-cylinder 'scale' Velie engine. This latter, because I'm a firm believer in keeping R/C engines cool - particularly when they are as overworked as they are in the usual scale model.

For the 'super-scalebuilder,' and the scale contestant, presentation data may be found in two books. The first, Joseph Juptner's 'US Civil Aircraft', Volume 2, has two excellent photographs, clearly showing markings on the prototype aircraft. The second book, 'Of Monocoupes and Men,' by John W Underwood, includes a picture of the primitive instrument panel as well as an in-flight shot.

The Velie Monocoupe is relatively simple to build and prepare for flight. The usual admonition, 'not for beginners' doesnt really apply, although initial test flights should be made by a thoroughly competent pilot. The construction is about as basic as a Megow 10 cent model of yesteryear..."

    ScaleType: This (oz6216) 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.
