D 9. Using epoxy securely glue the 1/4" plywood
wing bolt block (FUN1F18) in place. Notice that the
block is cut square and there is a slight gap towards the
rear. Simply press the fuselage sides up tight against the
wing bolt block u n t i l the glue cures. Add three pieces of
1/4" triangle underneath the block as shown in the pholo.
D 10. Install the outer pushrod tubes (PLTB011) by
threading them through formers F5 and F6 and then
through the OPPOSITE fuse side. Make sure the one that
goes through (the highest hole in F6 is above the other
where they cross. Allow them to extend about 1" past F4B
and 1" past the die-cut fuselage exit. Mark where the tubes
contact the formers and remove the tubes. Scuff up the
tube surface with 100 grit sandpaper in those locations and
replace in the fuselage. Glue the tubes in place with med/
thick CA.
D 12. If you want to install an antenna tube in the
fuselage, now is the time to do that. We normally use a
piece of pushrod tubing and secure it along the fuselage
bottom, exiting near (the rear of the fuselage. Be sure to
anchor the tube securely as (the maneuvers this plane is
capable of could knock it loose).
D 11. Cut the tubes off flush with the fuselage side and
apply some balsa filler around the tube. After the filler
dries sand everything flush with the fuselage side. (See
photo for this step in next column)
D 13. Securely glue the 3/32" die-cut stab bed
(FUN 1 F07) in place with CA. The embossed line on the
stab bed should be facing up. Make sure it is sealed prop-
erly so the slab will sit level without modification.
