Table of Contents

Aeromodeling has seen significant changes over the decades both in technology and preferences. Magazines like American Aircraft Modeler, American Modeler, and Air Trails were the best venues for capturing snapshots of the status quo of the day. All copyrights are hereby acknowledged.

This set of very detailed drawings of the Ryan ST-3, aka Army PT-21, aka Army PT-22, monoplane appeared in the July 1962 edition of American Modeler. I cannot make out the signature to give credit to the fine work. The artist included a lot of information that scale modelers in particular would be interested in such as cockpit materials, instruments, wheel and propeller sizes, etc. It also has a detailed drawing of the main landing gear oleo strut. Tables of the various commercial and military designations are included as well in the set of three drawings.

Notice:

The AMA Plans Service offers a full-size version of many of the plans show here at a very reasonable cost. They will scale the plans any size for you. It is always best to buy printed plans because my scanner versions often have distortions that can cause parts to fit poorly. Purchasing plans also help to support the operation of the Academy of Model Aeronautics - the #1 advocate for model aviation throughout the world. If the AMA no longer has this plan on file, I will be glad to send you my higher resolution version.
