So I?m at the stage of the fuselage build where you install a doubler on the seat rib for the autopilot option. If you don?t plan to ever install the autopilot system can you skip the mounting doubler and other brackets? I?d rather not add extra parts that I know I will not need. Do these provide any function other than mounting autopilot components? In other words, are they required for structural support of no autopilot system is installed?
