Ryan ST Sport Trainer

Description: A sport-scale military trainer

Designed by Henry A. Haffke, this attractive, relatively easy to build military trainer is made of balsa and ply; its tail surfaces can be made either of solid balsa sheet or built up for a more scale appearance. The plan shows details for several versions, and includes details to build the scale Kinner radial engine.
