X-Plane 9.70+ Let Aero 145. The Czech-produced Aero 145 was an re-engined version of the earlier Aero 45, replacing the Walter Minor with the more powerful, supercharged Walter M 332, developing 140 hp. It first flew in 1957, and was produced in great numbers and was a great commercial success. Here is my modest take at it; it uses some modified parts from Jacques Braults Let 200D Morava and the sounds are from Dataroots. It comes with three historical liveries. By Thibaud Duhamel.
