Apply some glue to all surfaces, tabs and slots, and then install the upper fuselage. Firmly press up and
down the length of the upper fuselage piece to ensure the two pieces are fully seated to each other. Do this a
couple times.
Wipe away any extra glue and check along the length for squareness. As with the bottom, it should
naturally be really close if not right. Tweak a little if needed.
As shown in the picture above, the motor mount and the upper fuselage are installed.
