Gluing the Second Pair of 18x18 mm Longerons (3.0 hours)

2026-09-08

After returning from my summer holiday, I found time to glue the remaining pair of 18x18 mm longerons to the fuselage. Not much else to report.

I spent a couple of hours fitting the longerons to the fuselage, cutting the notches and dry-fitting the parts. The gluing itself went smoothly. Since the longerons had been held roughly in position on the fuselage for a couple of weeks, little force was needed to hold them in place during gluing.

Now I need to clean up and sand the fuselage, then inspect all the joints carefully.
