Definitely a collectors item at this point. These were out just a few years before the end of Cox. They had a Cessna 182 and a Fairchild in the same series but the PT-19 I think were produced in lower numbers. The actual manufacturer was Kyosho as there was a tie between Cox and Kyosho back then, especially with the R/C cars before Kyosho became a Great Planes exclusive brand in North America. I would not be surprised if market value exceeded $500.00
