Finally, it’s time to start gluing on formers. We’ll
start with the back and work our way forward.
Here’s a photo of what the bottom of the
fuselage looks like when it’s partially framed-up.
You can use this photo as a reference as you
perform the following several steps.
❏ 13. Test fit, then glue formers 7B through 12B and
the bottom stabilizer mounts into position. Be certain
all of the formers are vertical and accurately align
with their position on the plan. Note: Twisted formers
will simply be straightened when the stringers are
added later. Note: Be certain the pushrod holes in
the formers align with the pushrod holes shown on
the plan.
❏ 14. Starting from the aft end, fit, but do not glue
formers 6B through 2B and both fuselage doublers to
the assembly. Be certain that the fuselage doubler
you cut earlier will be on the right side of the
fuselage—remember, the fuselage is being built
upside-down, so the right side is the side nearest us
in the photos. Note: Be certain that 3A faces forward
as shown on the plan.
❏ 15. Glue former 4B and the fuselage doublers—
only in the area of 4B—to the fuselage spars.
❏ 16. Proceed by gluing the remaining formers
(except the firewall) and the fuselage doublers into
position. As you proceed, bow the fuselage doublers
outward between the formers so they align with the
fuselage main spars and glue as you go.
❏ 17. Glue the firewall into position with 30-minute
epoxy. Use clamps, large T-pins or whatever means
necessary to hold the parts together and keep the
firewall in alignment until the epoxy hardens. #2 x 1/2"
[13mm] screws may also be used to help hold the
fuselage sides to the firewall. Tighten the screws
securely so the heads sink partway into the doublers—
the screws will be permanent.
❏ 18. Cut both 3/16" x 24" [4.8 x 610mm] gray
pushrod guide tubes to the length shown on the plan
for the stabilizer and rudder. Roughen the outside of
the tubes with coarse sandpaper, then slide them
into position, but do not glue.
❏ 19. Use the remainder of the 3/8" x 3/8" x [9.5 x
9.5mm] basswood stick leftover from the aileron servo
mount for the bottom of the fuselage across the
doublers. Glue the stick into position and sand the ends
even with the doublers.
❏ 20. Cut and glue seven 3/16" x 3/16" x 24" [4.8 x
4.8 x 610mm] balsa stringers into the notches in the
formers in the aft end of the fuselage. Any formers
that are twisted can be drawn into position as the
stringers are glued to them. Now glue the previously-
installed guide tubes to the formers.
❏ 21. Glue in the die-cut 1/8" [3.2mm] plywood fuel
tank tray. (The tray can be seen in following photos.)
