The major item on the list was the aileron brackets. It was a fun project in that there were a lot of different parts that needed mating to create these brackets. Also, there is a service bulletin (SB 16-03-28) which adds doublers to reduce the chances of cracking at the aft wing spar. Although it is not stricly necessary unless you observe cracking, I decided to pre-emptively apply the SB. Honestly it’s pretty straight forward if you do it during build, and becomes a major pain if you need to do it later. After taking my time with the first bracket, the rest were pretty straight forward, and nothing major to report. One minor thing to note…why don’t they have blue vinyl on the smaller parts? Instead, they use these stickers that are a real pain in the butt to remove. Lots of acetone fixed the problem.
