About this Plan

Ryan ST. Scale model for .19 power and RC.

Quote: "The Ryan ST signaled the beginning of the sleek, streamlined monoplane era. First flown in 1934, 181 production models were built, of which the YPT-16 was the first low-wing monoplane trainer to be used by the Army Air Corps.

Perhaps the most exciting trend in Radio Control today is the scale or scale-like flying model. By Scale Flying Model I mean a realistic, good looking ship that the novice R/C'er can build and fly. Most modelers have been avid aviation enthusiasts since youth. What could be more fulfilling, then, to see airborne that dream ship of years gone by? For me that dream ship is the Ryan ST.

When the Ryan ST first flew in 1934, it shared a sky filled for the most part by wood and cloth biplanes. Its appearance marked the end of the biplane era and signaled the beginning of the sleek, streamlined monoplanes. Wealthy sportsman pilots were quick to appreciate the racy good looks and flashing performance of the ST, and most of the 181 airplanes built found homes among private owners. A few Ryan ST's were purchased by the US Army and dubbed YPT-16. These aircraft had the distinction of being the first low-wing monoplane trainers used by the Air Corps.

Our scale Ryan ST seems to reflect many of the qualities of its full-sized counterpart. Not only does it have a great deal of eye appeal on a low flyby, but also turns in a good scale-like aerobatic performance. The one thing that has been bred out of our model is the tricky ground looping tendency of the full scale version.

If you have looked over the plans and photos and waded through the nostalgia portion of the text, you must be ready to cut wood. Some of the construction may look a bit light to those of you who are used to hanging a .60 on your creations. Fear not, however, all structure is plenty adequate for a .19 sized ship. Just be sure to use good glue and follow the wood densities suggested. That round fuselage looks pretty tough, let's start with it.

Begin by cutting two Basic Fuselage Sides from 3/16 in soft sheet. Glue 3/16 x 3/4 Basic Longerons to sides, being sure to have one left and one right side. Add the 3/16 soft sheet Forward Doublers, the 3/16 x 3/5 Forward Longerons, and the 3/16 square Corner Block. Next, glue on the 1/16 ply motor mount Webs and the 3/8 square hardwood Motor Mounts. Set the two side assemblies aside to dry and cut out all of the Formers. Also cut out the 1/16 ply Servo Floor. The 1/16 ply may sound a bit thin, but is plenty good if you attach your servos with the foam tape made by Rocket City. If you prefer to use screws, add an additional 1/16 plywood lamination only in the area of the servos.

When the two sides are dry lay the right side over the plans and glue in F2, F5, and F6. Then set the left side down on top of the formers, being sure that all is square. Allow to dry thoroughly. Glue in the Servo Floor, and then the three F4's. Also glue in two F3's. Allow to dry thoroughly, once again checking the fuselage to be sure that it is square..."

    ScaleType: This (oz6002) 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.
