of the fuselage side. Use the die-cut 1/8" plywood
former F-5 to help you position the doubler (do not
glue the former in until told to do so later). Notice that
the pushrod exit holes do not line up (this is normal
and makes the pushrod installation in later steps
easier). Apply several beads of medium CA to the
doubler and position it on the fuselage side. When
it is aligned properly, press it firmly down to spread
out the beads of glue. Repeat this step for the other
side. Be sure to make a RIGHT and a LEFT.
fuselage doubler over the inside of the fuselage
sides. Notice that it should fit perfectly at the very
front of the fuselage, and then be offset 1/8" in from
the edge of the fuselage sides most of the rest of the
way back. The photos and plans will help you
determine the proper location of the doublers. Use
the front edges and the lock notch in the fuse side
near the lower aft portion of the doubler to align the
doubler.
8. Apply medium CA to the doubler and press it
carefully in position. Apply thin CA around the all
edges of the doubler to reinforce it. Glue the
doublers to the inside of both the left and the right
fuse sides.
AT THIS POINT YOU MUST DECIDE
WHETHER YOU ARE GOING TO BUILD
A TAILDRAGGER OR A TRIKE GEAR
MODEL. THE POSITION OF THE LANDING
GEAR DOUBLER (GD) DEPENDS ON THIS.
area. The die-cut 1/8" plywood gear doublers (GD)
may be placed in two different positions (forward for
taildragger gear, aft for trike gear). Note also the off-
center slot in the doubler. The slot should be off-
center toward the aft end of the left fuselage side,
and the forward end of the right fuselage side. Glue
the gear doublers in the position chosen.
10. Glue the right and left die-cut 1/8" balsa
forward fuse bottom pieces together with thin CA.
Add medium CA to any gaps.
11. Glue the right and left die-cut 1/8" balsa
middle fuse bottom pieces together with thin CA.
Place the die-cut 1/8" balsa aft fuse bottom piece
into the notch at the back end of the middle fuse
bottom. Notice that there is a gap in the middle. This
is for former F-4 to key into later. Check that these
parts are properly aligned by positioning them over
the fuselage top view on the plans. Glue with thin
CA. Add medium CA to any gaps.
