Dynaflite DYFA2016 - Manual (Page 11)

Skip to step 11 if you will not be building the
functional rudder.
Q 8. Cut a 36" outer pushrod guide tube to a length
of 29". Use coarse sandpaper to roughen the
outside so glue will stick. Slide the tube through the
exit slot in the rear of the fuselage until the front of
the tube extends past bulkhead C the same amount
as the elevator guide tube (this should be about 2").
Make sure the rudder guide tube does not interfere
with the fin LE or the elevator guide tube. If it does,
adjust the position of the exit slot until there is
no interference.
Q 9. Glue the guide tube to the fuselage side in the exit
slot with 30-minute epoxy and microballoons or just
thin CA. If you use thin CA, fill the slot around the guide
tube with lightweight balsa filler such as Hobbylite".
LJ 11. Glue the elevator guide tube and the rudder
guide tube (if you have one) to the inside of the
fuselage sides in a few locations with epoxy.
Because of the angle at which the guide tubes enter
the fuselage at the rear, they should naturally contact
the inside of the fuselage sides in a few spots. This is
where you should glue them.
U 12. Sheet the bottom of the fuselage in a cross-grain
fashion with the remainder of the 1/16" x 3" x 24"
balsa sheet you used for the top of the fuselage.
Q 10. Use your bar sander and 80-grit sandpaper to
sand the exit tube and filler flush with the fuselage side.
1-1 13. Cut, but do not glue, a strip of 1/16" x 3"
balsa to fit on the bottom balsa sheeting joining the
aft edge of the bottom ply sheeting as shown on the
plan. Taper the aft edge of the sheet. Glue it
in position. Use your bar sander and 80-grit
sandpaper to sand the bottom sheeting even with the
fuselage sides and plywood sheeting.
Q 14. Make the tail skid from a piece of leftover
1/8" plywood. You can glue it now to the bottom
sheeting in the location shown on the plan or you
can wait until after you cover the fuselage.
