Michael good show on the flying. It is a good feeling when you get to do it on your own. Building also has its rewards. Your build and the covering looks very good. There is a learning curve to using Koverall. My LT-40 is the second time using it. I started covering the fuselage and found I was short on Koverall. I had to be a bit judicious applying what I had. I used dress liner on the bottom but the dress liner-Koverall seam looks terrible. But it's on the bottom so it will not be easily seen.
I'm going with latex so it will be interesting to see how it turns out. I'll be spraying too.
