Attach the wing centre section to the fuselage and secure it with the M5 nylon bolt. Attach and secure the tail surfaces to the tail boom with the push rod tubes installed in their holder (the holder prevents the tubes from getting loose and keeps any unwanted play in the elevator and rudder linkage next to zero). Slide the tail boom onto the holder on the fuselage front part. Thread the push rod tubes through the holes in F10, F8 and F7 formers.
Check that the fuselage is straight-looking from above; align the wing and the horizontal tailplane with their trailing edges parallel. Once satisfied use 30min epoxy to secure the tail boom in place. Double-check the correct alignment of the wing, fuselage and tailplane before the glue hardens.
