I made significant progress today with installing all of the rivets possible on the RT Stabilator before installing it on the fuselage. The top of the stab rivets mostly have to wait until it is fitted to the fusealge becasue of deburring and rivet access issues, per plans. I also trimmed the fiberglass stab tips and installed the tip ribs. I will be abel to install the tips on the stabs after the ruddervators are fitted. Finally, I started drilling the LT Stab front spar. All in all it was a productive weekend day.
