Fig. 29
- Glue the wing saddle doublers R2 to the inside of the
fuselage sides R1. Take care to keep the edges flush.
Figs. 30 and 31
-Trim the balsa fuselage longerons R28 to fit and glue them
to the fuselage sides R1 in the positions shown on the
plan. Sand the longerons to a taper at the tail end of the
fuselage - see plan view.
Fig. 32
- Pin down one fuselage side R1 on the building board and
glue the formers R4 to R6 and the servo plate R7 to it, fit-
ting the tabs into the slots; keep them at right-angles to
the fuselage side.
Figs. 33 and 34
- Place the second fuselage side on the formers, checking
at the tail end that the parts are lined up correctly; the
fuselage sides must not be twisted or offset relative to
each other.
- Glue the nose former R3 in place.

- Glue the second fuselage side in place, installing the wing
supports R8 to R11 at the same time.

mers R4 to R6 only.
Fig. 37
- Glue the fuselage bottom doublers R13a + R13b in place
over their full area.
Fig. 38
- Allow the glued joints to set hard, then curve the front part
of the bottom panel R12 down to meet the former R3, and
glue the parts together.
