Finish The Fuselage - GREAT PLANES RV-4 Instruction Manual

9. From left over 3/32" [2.4mm] balsa sheet cut a piece to
fit between the two wing fairings and a piece to fill the front
of the fairing at the leading edge of the wing. Glue them in
place. Then sand the wing fairing to blend into the wing.

Finish the Fuselage

1. Locate the 3/32" [2.4mm] die-cut balsa cockpit
doublers (2- CDB and 2-CDF). Note: Doublers CDF are
shorter than CDB.
2. Glue the CDF doublers to F4A. Be sure to set them
back from the edge of the fuselage 3/32" [2.4mm], the width
of the fuselage sheeting. When positioned properly they
should fit the outer edge of F4A.
3. Glue the CDB doublers to F5A. Position them the same
way as you did for CDF.
4. Using your plan as the reference, mark the location of
BK and IP by drawing lines across the floor of the cockpit.
5. Locate die-cut 1/8" [3mm] balsa formers IP (instrument
panel) and BK (back seat). Glue former BK on the forward
most line on the cockpit floor and glue IP on the rearward line.
6. On the plan you will find the paper cockpit sheeting
template. Use this as the pattern and cut two cockpit sides
from 3/32" x 4" x 24" [2.4 x 102 x 610mm] balsa sheet.
7. Trial fit the cockpit sides to one side of the fuselage
between F4A and F5A. Sand the cockpit sheeting as
needed to fit. Once you are satisfied with the fit, glue the
cockpit sides to F4A, F5A, IP and BK. Hint: You may need
to wet the balsa wood to bend it without cracking.
8. Repeat step 7 for the opposite side of the cockpit.
