Looking great! Hey, I built this very same kit 3 years ago. It turned out so well, that, to my surprise, it placed Gold in the Civil Aviation Category at JaxCon.
I enjoyed the build immensely. The aftermarket stuff wasn't available back then. I scratch built most everything that wasn't in the box. If you want to see how mine turned out, search for my entry called "1/48 Zlin 50M Stunt-Aerobatic plane" from May of 2018 in this Forum Subject. I'm excited to follow your build tutorial. I hope you like it as much as I did.
