About this Plan

Ford Trimotor (Tin Goose). Radio control scale model. Wing area 900 sq in, for 1 x .60 and 2 x .049 engines.

Quote: "The legendary all metal Ford Trimotor first rolled out of Ford's Dearborn, Michigan factory in 1926. Forty-eight years later, the 'Tin Goose' is still flying. You can combine history and nostalgia with this easy-to-fly Ford 5AT constructed of foam and corrugated cardboard.

Almost forty-eight years ago, in July of 1926, the first all metal Ford Trimotor airplane rolled out of the Ford shops at Dearborn, Michigan. Incredible as it may seem, there are still several of these big three engine all-metal airplanes still flying. No other airplane contributed more to the early development of our airline system than the Ford Trimotor. It was the first to fly on a regular scheduled airline operation, and the first to carry two uniformed pilots and a flight steward. The Ford could fly equally well on any two of its three engines, and could maintain level flight on only one engine. The Tin Goose could land in any small field and could take off in three times the length of a football field fully loaded! One of the most famous Trimotors of all was the Floyd Bennett. Admiral Byrd flew this airplane over the South Pole on Thanksgiving Day, 1929.

Two models of Ford Trimotors were built, the 4AT and SAT. The former had a wing span of 74 feet and was powered with Wright J5 or J6 engines of approximately 225 horsepower each. The larger 5AT, which was our choice for a model, was nearly 78 feet in wingspan and was powered with three Pratt and Whitney Wasp engines of over 400 HP each.

Most of us who construct and fly small radio controlled aircraft have, at one time or another, fallen in love with a particular design. In my case, it ran from early WW I biplanes like the Se5 and Fokker D7 to WW II fighters such as the P40 and P63. I have always been partial to scale or semi-scale and although I enjoy aerobatics very much, I have no interest in competitive pattern type flying.

I must say that I even surprised myself when suddenly I just had to build a Ford Trimotor. Immediately the thought flashed through my mind of a beautiful big silver bird powered with 3 Wankels climbing into the blue while the crowds applauded and cheered. There was one small problem however, and that was how to obtain a corrugated effect...

    ScaleType: This (oz9426) 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.

* 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.
