Chapter 6 Empennage Date 2/15/00 Procedure VS-1 The first thing to build is the Vertical spar. Layout the shape of VS-408 I used a CNC vertical mill to produce and at this time I pulled all the parts from the kit that could produce on a CNC mill and made them. They include all the brake peddle parts, Instrument panel. I assembled the spar flange VS-403 to the spar reinforcement plate VS-408 after all the parts had been primed. (Image) 014
