8. Temporarily place the stab with elevators and
the fin with rudder on the fuse. Rest the control horn
on the rudder.
❏
9. Center the rudder. Use a fine point felt-tip pen
to mark the pushrod where it passes the hole in the
servo arm.
❏
10. Unscrew the clevis from the aft end of the
pushrod. Pull the pushrod partway out of the fuse
from the front. Bend the pushrod at the mark, then
cut off the excess wire, making certain you leave
enough for the FasLink. Take the servo arm off the
rudder servo and connect it to the pushrod with a
FasLink. Slide the pushrod back into the fuse and
connect the servo arm to the servo. Center the servo
and the tail gear. Temporarily tighten the set screw in
the wheel collar locking the rudder and tail steering
pushrod together.
❏
11. Make the pushrod for the elevator the same way.
❏
12. Use a 3/32" x 3" x 40" [2.4 x 76 x 1016mm] balsa
sheet and a 3/32" x 3" x 36" [2.4 x 76 x 914mm] balsa
sheet to make a skin to sheet the left side of the fuse
from the main stringer up to the middle of the first 1/4"
x 1/4" [6.4mm x 6.4mm] stringer. Save the remainder of
the 36" [914mm] sheet for the other side.
❏
13. Cut a slot in the aft end of the fuse skin to
accommodate the rudder guide tube.
❏
14. Loosen the set screw in the wheel collar that
joins the rudder and tail steering pushrod. Unscrew the
clevis from the aft end of the rudder pushrod. Slide the
pushrod forward through the hole in former 5D.
❏
15. Mix a small amount of 30-minute epoxy and
microballoons. Apply the mixture around the rudder
guide tube where it will exit the slot in the fuse skin.
Position the fuse skin on the fuse. Glue the skin to
the main stringer only. Wet fuse skin with water or
spray window cleaner, then glue it to the rest of the
stringers and formers. Make sure the slot in the skin
around the guide tube is packed with epoxy and
microballoons, so the slot will be filled when the
guide tube is sanded flush with the fuse skin.
❏
16. Make a fuse skin for the other side the same
way using the remainder of the 3/32" x 3" x 36" [2.4
x 76 x 914mm] balsa sheet and an additional 3/32" x
3" x 40" [2.4 x 76 x 1016mm] balsa sheet. Glue the
fuse skin to the right side of the fuse.
