DISCONTINUED MPM 72084 Ryan PT20/SMT-S2

The Ryan PT-20 (another designation: Ryan ST) is an American-made sports and training aircraft, manufactured by the Ryan Aeronautical Company. The prototype's flight took place in 1934, and the machine entered mass production shortly thereafter. About 1,550 aircraft of this type were built in its course. The machine was powered by various types of engines, such as Menasco B4 95 HP or Menasco C4S2 165 HP.

The Ryan ST was developed as a simple and relatively cheap training and sports plane. It had a tandem cabin, it was also a low wing with a fixed, wheeled undercarriage. The machine was mostly made of steel and aluminum. In the course of serial production, many versions of this aircraft appeared, such as: ST-A (version adapted to aerobatics), ST-B (single-seat version) or STM-2 (version dedicated to Dutch forces stationed in Southeast Asia). The plane - under the designation PT-20 - was used by American aviation.
