This model was given to me by friends of a deceased modeler who had nearly finished building it from an unknown plan and short kit about ten years ago. It was set up for a 2-stroke glow engine and used simple plastic covering.
They asked me to "fix it-restore it-finish it" and get it to fly to honor the memory of our old friend. I stripped it completely to bare balsa, corrected many deviations from scale accuracy by including such details as accurate wing and tail fairings and fully-plywood-sheeted wings, added a mount for the AXI motor and the LiPo and ESC, and gave it a proper scale finish using Stits Lite covering and finishing products.
The PT-19 now performs beautifully...a low pass at reduced power in order to present the appearance of scale speed makes it easy to believe you are looking at a full scale airplane. It has become one of my favorite models to fly.
