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.

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.
