wings are aligned correctly.
7. Ensure that the drain plugs on the root ribs of the main wing at
the leading edge are installed
8. Insert the right spar end into the fuselage with the flaperon in the
neutral position and the dihedral angle approximately correct.
9. Insert the left spar end into the fuselage, also with the flaperon
in the neutral position and the dihedral angle as such to slide into
the self-aligning bush of the other wing.
10. Insert the main pin when the wings are fully in.
11. Secure the main pin by rotating the pin into the spring- loaded
lock pins.
