Brief Description: Finish right spar, start left flaperons
Marked centerline on upper strut fitting; placed right spar into position with the fitting held by an AN7 bolt. Sighted the centerline thru the pilot holes in the spar. Lightly drilled to mark the hole locations. Used a small angle drill to lightly drill on the upper side as well.
Removed spar and drilled thru the fitting. Updrilled in steps to the final 1/4" - AN4 bolt hole size. Installed hardware and torqued to spec. Painted the rest of the spar (only did the ends previously).
Tried to fit the left flaperons. Concerned about the lack of correct spacing between the top of flaperon and bottom of wing trailing edge. Went home to study and fabricate a spacer as suggested by Zenith.
