Aligned upper Winglets and marked Wing cutouts. Note: Correct placement of Port Winglet antenna on inboard skin means the coax fouled the top skin and needed relieving. Hmmmmm.
Prepped lower Winglet bubble and applied 1 x UND patch and 1 x BID cover.
Heated left Wing bubble #2, injected resin and clamped. 2 to go.
Holding measurement A steady, and trying to find B. Mark position with third hand...
