Then push the back part of the horizontal
fuselage section down over the rear part of the
wing support.
Slide the whole horizontal fuselage section
forward as far as it will go.
Then lift up the rear part of the horizontal
fuselage section and slot it down over the fin and
work it down gently.
Work the whole horizontal fuselage section
backward bit by bit until the rear slot fits neatly
into the slot in the fin.
Glue the horizontal fuselage section in place with
UHU Expanded Polystyrene Glue or other foam
safe glue.
Next take the wing parts and sand the upper
surface of both around the edge to form a
smooth rounded leading and trailing edge.
