in
the guide slots.
Gently
move the wing until there
is
an
audible click as the lock rings engage.
Next insert the left wing into the fuselage and ,
by
appropriate movement of the wing
tips; engage the two spar end spigots
in
the bearings

The push connector sleeves must cover the
red
rings
on
the control rods.
The connections for ailerons and airbrakes
lie behind the main spar.
The short connecting rods
in
the fuselage are fitted with quick-locking mechanisms,
which must
be
coupled to the ball connections
on
the wing control push rods.
To ensure the security of the connection the following check must
be
carried out.
When the connecting rods are assembled,
visually check that the locking wedges are
sufficiently engaged
so
that they stand out some millimetres from the catches. Then, by
slight rotation and pushing and
pulling, try to pull the connecting rods from the ball
connections. If the connections remain fixed under a load of approximately
Skg
the
controls are correctly attached.
