ZTS was a Polish company, comparable to Smer and KVZ in the overall impression the models made, and especially comparable to KP in their choice of ostensibly native subjects––Polish, in their case. The fit and detail was about comparable to KP and Smer––deporable but, with effort, could produce a nice-looking result. What was special about ZTS was its scarcity. In my seven years living in communist Czechoslovakia, I built many KP kits twice. The whole time, I saw a grand total of one ZTS kit, the RWD-5bis. This civil airplane set some kind of mileage record after being modified to replace a passenger seat with a fuel tank. The tiny box was covered with dark, foreboding art––just the thing to reinforce the mysterious aura of this unknown brand. Opening the box, however, revealed a lack of pilot figures, a profound disappointment.
