I trimmed, drilled, nutplated and installed all the panels, but without drilling any of the holes in the longerons or front floor at this point. I want to check clearances before drilling into critical components of the fuselage.
There was a lot of trimming to be done on the battery cover to make if fit the forward panel. The forward panel flanges also needed to be trimmed down much further than to the 7/8" measurement called for in the plans, but it's a nice fit now.
