I am still waiting on a reply from Kerry at Sonex so I will hold off another day to progress. I am also hoping that my deburring wheel and mandrel for my drill comes in tomorrow to help with trimming the skin of the tail down. I went through the parts to see if I had all the things I need (except the skin) for the sport acro mod. I want to do that so I needed an idea of what I had. Went through some other plans pages to check on some parts. FYI it looks like the parts will cost about 220 plus shipping for the sport acro parts.
