Align lower wing sheeting with tabs on main spar and place sheeting panel on spars and ribs.
Check for correct fit, then glue in place and briefly press onto a flat surface.
Remove any residual glue from inner edge
of servo frame.
At rear edge of wing secure upper an lower
wing sheeting with two strips F11 and
clamps, then place outer wing panel on
supports. Make sure front edge of wing
sheeting is flus with front end of supports.
Weigh down wing panel evenly on supports

Cut out aileron along engraved lines and carefully sand sheeting
material and ribs flush with spars. Sand front end of aileron flush
with F41, glue aileron leading edge F55 (3 mm balsa) to F41
and bevel for sufficient control throw.
Place wing upside down on building board and replace aileron
in cut-out.
Make up control linkage from clevis F57 and threaded rod F56,
cut to length and make a Z-bend at free end. Attach control
linkage to servo arm.
Use control linkage to mark position of control horn on aileron.
Use file or razor saw to create slot for control horn F53 in
aileron and glue control horn in place.
For aileron control use servos with a maximum thickness of
8 to 10 mm.
For standard 10 mm wing servos cut to length four 20 mm
servo mounts F51 (5×3 mm spruce). Cut off bottom servo
mounting flange, align servo with servo arm centred in slot
of servo tray F50, hold in place and glue servo mounts to
tray with a drop of white glue or medium CA.
