About this Plan

Porterfield Turner 50. Free flight rubber model.

Quote: "One of the newest arrivals on the American light plane tarmac, the Porterfield-Turner 50 is rapidly warming the hearts of many private flyers. Of course, all of you balsa bashers can't afford to shell out the 4995 for this buggy - but you can build a top-notch miniature of the job from Claude D McCullough's simple plans and instructions.

WHEN ROSCOE TURNER rocketed his stub-winged racer to victory at the National Air Races last year, he brought to a brilliant close a long and celebrated racing career. After years of herding screaming bundles of horsepower around the pylons and making record-smashing hops, the famous Flying Colonel has now turned to bringing aviation safely and economically within the reach of John Q. Public through the medium of the light-plane.

For Roscoe now is vice-president at the Porterfield-Turner Aircraft Co. whose famous president EE Porterfield has built more than 1,000 airplanes. The Kansas City company currently produces a number of excellent airplanes from $995 up.

The Porterfield-Turner 50 is a two-place monoplane using the Continental 50 hp engine, completely covered with a new type cowling which provides forced draft cooling and an effectively streamlined nose section. Boasting striking lines externally, the interior provides effec-tive comfort In a roomy upholstered cabin. The 50's top velocity is well over 100 mph, and at the cruising speed of 92, the ship turns in 27 miles per gallon of gas. Yes, this lightplane combines the factors of safety, per-formance, economy, and comfort

As a model, the Porterfield-Turner has much to offer to the builder, both beginner and expert. Although the original ship was built as a sport and display craft, it has already won a flying scale contest and consistent-ly turns in flights of over 1 minute. The construction is very simple, and although strong and rigid, the plane weighs only 1.3 oz without colored dope.

A successful flying scale model must combine good looks with good flying qualities, and these can only be obtained through patience and careful workmanship. Spending a few cents more and getting Grade A balsa and good quality materials will produce a much better plane. A glance at the Bill of Materials will indicate how cheaply the '50' may be built.

But we have a job to do - so let's retire to the workshop. Study the plans carefully before beginning and make sure you understand all of the constructional details. Collect together all your tools now. Ready? Then let's begin.

Fuselage. Connect at B-B the plates showing the side view of the fuselage. Using the black shaded portions as a guide, construct the two sides of the main framework, one on top of the other. Pins will hold the curve of the outside 1/8 sq. longerons until the 1/16 by 1/8 cross-pieces have dried. Remove the two sides and separate them carefully with a razor blade. With the top view to indicate the width, cut the various spacers. Using books or other heavy objects to hold them in position, cement in the spacers, forming the rectangular portion of the fuselage..."

    ScaleType: This (oz1303) 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 https://en.wikipedia.org/wiki/Porterfield_Collegiate
    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.
