GREAT PLANES RV-4 Instruction Manual page 24

13. Locate the die-cut 1/8" [3mm] plywood forward right
fuselage top (RFT) and the forward left fuselage top
(LFT). Glue RFT and LFT together as shown.
14. Locate the two die-cut 1/8" [3mm] plywood aft
fuselage tops (AFT). Glue them together the same way you
did the forward right and left fuselage top.
15. Glue the forward fuselage top to the aft fuselage top
as shown. This forms the fuselage top and will be referred to
as the fuselage top throughout the construction process.
16. Locate the two die-cut 1/8" [3mm] balsa aft fuselage
bottoms (AFB). Glue them together the same way as the
fuselage tops.
17. Pin the fuselage top over the plans. Important! The
fuselage will be assembled on the plans upside down. When
you are assembling components that reference the right or
left side of the fuselage, take the time to be sure you are
working with the correct side of the fuselage.
18. On the inside of the left and right side of the fuselage
glue the die-cut 1/8" [3mm] plywood wing saddle doubler
(WSD) in place as shown on the plan.
19. Locate die-cut 1/8" [3mm] plywood formers F3, F4
and F5 as well as die-cut 1/8" [3mm] balsa formers F6 and
F7. Test fit formers F3 through F7 onto the fuselage top at
the location shown on the plans. When you are satisfied with
the fit, glue the formers in place to the fuselage top. Use a
small modeling square to assure that the formers are
perpendicular to the fuselage top.
20. Glue the right side of the fuselage to the fuselage top.
When completed, glue the left side in place.
21. Locate the die-cut 1/8" [3mm] plywood left fuselage
doubler (LFD) and the right fuselage doubler (RFD).
