About this Plan

Ryan ST. Radio control scale model 1930s two seater trainer.

Quote: "Very few modelers need an introduction to the Ryan ST. In real life it was the first low wing trainer used by the US Army for pilot training. The ST had an aluminum monocoque fuselage and fabric covered flying surfaces. This was not especially hard to duplicate. The real beauty of the original was in the smooth cowled in Menasco 4 cylinder engine and the ultra streamlined wheel covers. The only problem the modeller will encounter here is solved by a few sheets of sandpaper and a lot of patience!

For the benefit of those who may build and enter the R/C Ryan in a contest, here are the facts concerning its fidelity to scale. All outlines, ratios and locations are true to scale. The only departure was the stab-elevator which was enlarged slightly for obvious reasons. Using the same reasoning we dispensed with the flying wires and compression strut from fuselage to wing which supported the impact of the landing gear on the full scale craft. Any other scale questions can be answered by the scale we used which was 2.2in = 1ft.

In outlining the construction procedure, we will spend most time on those areas which may give the most trouble. The construction is of an average nature and should offer no trouble or problems. The fuselage is actually built in three parts and each is completed, except for final sanding before they are joined together. The mid section is basically a box. Cut and mark off the former (FS) locations on two identical pieces of hard K" sheet balsa as per the basic side outline..."

Here is the last Ted Strader airplane plan I can get you. This is a scale design which was not usual for him. The model scale is 2.2"/foot, so I scaled the plan to 66" wingspan, which was corroborated by the stated wheel diameter. This was a fairly large plane in its time, and even though it spans 5 1/2 feet, it is powered by a .19. I can't imagine anyone today using anything smaller than a .40, but it was a different mindset back then. Most planes were rudder only and you wanted just enough power to maintain a gentle climb when flying straight.

    ScaleType: This (oz8237) 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/Ryan_ST
    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.
