I did some work on the vertical stabilizer. One of the things I read up on this kit is that the rudder was pretty ineffective and most were leaving it off to save weight. I decided to try and increase it's effectiveness by making it a flying surface. I hope I'm not making a mistake but I decided to copy the flying elevators and make the vertical stab flying as well. The elevators are 30% of the surface area ahead of the pivot. I did the same for the rudder. Here are some pictures. I am going to have to make sure the linkage is very stiff and strong with no slop.
I purchased a carbon fiber stab tube assembly to use as the pivot. I took the outer sleeve and cut some teeth into it and used it as a drill to open up a clean hole in the foam at the proper dimension I calculated.
Cut some teeth into the end of the CF tube to use as a drill.
