IMPORTANT - Read this whole paragraph
before gluing anything in place!
D 8. The pushrod outer tubes should be installed now. Due to
the number of pushrods available today and the fact everybody
seems to have their own favorite, we have not included pushrods
in this kit. You are free to use whichever brand of pushrods you
desire. The formers already have notches in them to fit the
majority of pushrods available You can also use an extra
pushrod tube or (similar) to route the receiver antenna down the
fuse if you wish If you want to use a tube for the receiver
antenna it should be installed first. Determine where you will
put the receiver (normally between F3 and F4) and route the
antenna tube to the compartment The antenna tube goes in the
lower former notches and will be glued between the rear fuse
doublers to the fuse bottom The elevator pushrod goes along the
right fuse side and will be glued in place above the antenna tube.
The rudder pushrod goes along the left fuse side and just sits on
top of the fuse side until the fuse top sheet is installed You may
have to drill holes in some formers to suit you installation Once
you have all the tubes positioned where you want them, mark on
each tube where the glue will be applied Remove the tubes (one
at a time) and scuff the outer surface with coarse sand paper where
the marks are. After all the tubes are back in place, apply med
or thick CA wherever necessary to securely glue them in place
BEHIND FORMER F6 ONLY! Do not glue them in place in
front of former F6 until after the servos and wing bolt blocks
are installed.
D 9. Trial fit the 3/32" Balsa Rear Top Fuse Sheet (SPT1F05)
in place with the rudder pushrod cut-out on the left side of the
fuse. When satisfied with its f i t apply a bead of med or thick CA
along the 1/8" balsa stringers, the fuse doublers, formers F6 and
F7 and the fuse sides and glue it in place.
D 10. Cut pieces of 1/4" Balsa Triangle (BAL141) to fit
between all the formers If you built the ballast box these pieces
should be approximately the following lengths:
two pieces - 3" long
two pieces - 3-3/16" long
two pieces - 3-7/16" long
two pieces - 1-7/16" long
two pieces - 3-1/4" long
two pieces - 4-7/8" long
one piece - 1-5/16" long
These pieces should be glued with med or thick CA They are
pressed into the corner between the fuse bottom and the fuse
doubler in the following places
Glue the 3" long pieces between formers F2 and F3.
Glue the 3-3/16" long pieces between formers F3 and F4.
Glue the 3-7/16" long pieces between formers F4 and F5
Glue the 1-7/16" long pieces between formers F5 and BB1.
Glue the 3-1/4" pieces above the towhook plate
Glue the 4-7/8" long pieces between formers BB2 and F6.
And glue the 1-5/16" long piece along the bottom between
formers F1 and F2 to seal the gap there.
