Chapter 14 – Central Section Spar

In this chapter I will produce the Centralsection Spar. This is the connection between the wings and the fuselage and thus a very important piece. It’s a hollow beam with several hardpoints embedded for mounting the wings as well as for the aft seat belts (shoulder harness). As usual I started by reading as many builder-logs as I found, to learn what kind of challenges other builders have had.
