When Cox PT-19's were still available, I could find them in second hand stores, some times as cheap as .50 cents, after people did spring cleaning. We used them in our club to teach kids to fly. They flew ok with a pusher prop running clockwise. Still have four, but suspect the plastic is too brittle to fly. I used to go to the field {in my early twenties} to enjoy the dads try to fly their kid's new Christmas present. After the smashup, I began to see the kid,s face and realised it was the first time they saw dad screw up. We began to show up at the field after holidays and offered to teach the kids to fly. It worked a lot better and they got to take the whole plane home.
