Thanks Carlos!
Yesterday I worked on correcting the rear of the fuselage and I built a second prototype, adding a canopy to both (that will need some revisioning imo). It's honestly not that different from the first prototype as it comes from mostly the same measurements; I will probably show both prototypes once I get the landing gear and aerials all sorted out. Today, however, I got a little sidetracked and went ahead and digitalized a good bit of the design, including all of the different versions' tails according to the Yefim Gordon book
I will test build these parts tomorrow, but I figured I'd post just to indicate the direction of the project (although two pieces still lack panel lines):
