Quote: "A 1/8 Scale Model Of A Golden Age Classic - For .25-.32 2-Stroke Power. Stinson SR5-E Reliant N by Ron Peterka.

I never met Tom Laurie, he died a few years ago, but I know and respect his abilities. A lifelong modeler since the thirties, several of his free-flight designs were printed in the Frank Zaic Yearbooks, but his most outstanding project, in my eyes, is his restoration of N14187, a full scale Stinson SR5-E Reliant airplane.

Even though Tom never managed to get a pilot's license, he persevered as a labor of love. When it was finished, Tom had to get a qualified pilot to fly it. He spent ten long years restoring this classic 'straight wing' Stinson to such a high degree of perfection that it was awarded '1984 Grand Champion Antique' at the prestigious EAA Convention at Oshkosh against some of the finest antique aircraft over presented for competition.

This beautiful aircraft had been on display at the Gillespie Field
hangar of the San Diego Aerospace Museum in San Diego, California, untill recently when it was sold to a private owner. Excellent 3-views and photo paks are available from Bob Barka.

The SR8 through SR1O 'Gull Wing' Stinsom: are perhaps better known, but the SR5-E is a pretty design and a little easier to model with the constant chord wings compared to the highly tapered wings of the SR-8 or SR-10.

This 1/8 scale model is a highly detailed model of Tom's Stinson, with measurements from the real craft taken to document almost every visible feature. Wing rib spacing is scale. Wing flaps, called 'speed arresters' by Stinson, were an optional feature in 1934 and are installed on N14187. It was common in those days for each airframe to be highly customized to meet the customer's requests.

Construction. If you decide to build this model, be advised that it is a somewhat complicated effort, not at all a beginner's model, and will require some ingenuity in some areas. Any modeler who has built from plans should enjoy the challenge of this project. Please use these plans as a suggestion for one way to build the model, and feel free to change materials and detail design to suit yourself and your skills.

At this time few applicable commercially manufactured parts are available. Fiberglass Master Inc offers a 5-1/2 in diameter Waco SRE cowl and they offer wheel pants that may fit for you. l enjoy the challenge of making my own pieces, so I built composite epoxy/glass cowl and wheel pants using foam for patterns, covering them with three layers of 3 oz. satin weave fiberglass cloth and using E-Z Lam epoxt resin to form a hard shell; same thing for the upper windshield and forward cockpit area..."

* 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.
