The Ryan STs were a series of two seat, low-wing monoplane aircraft built in the United States by the Ryan Aeronautical Company. They were used as sport aircraft, as well as trainers by flying schools and the militaries of several countries.

The ST-A was further developed as the ST-A Special, with a super-charged 150HP Menasco C4-S engine of increased power.

The model is scaled to approximately 1:3.8 and attention was paid to a true to original appearance and best flight characteristics. The model was designed for electric drives but can also be operated with an internal combustion engine about 30cc displacement.
