Started on the Vertical Stabilizer. 2 Main spars in this build. The plans called for M3 rivnuts but the factory has upgraded this to M4 sizes. Enlarging 14 holes had to be done to the new sizes. There was a slight alignment issue of some of the nested parts that had to be dealt with. The spars have been assemble and test fitted on the fuselage tail to check for M4 screw and rivet alignment.
