GREAT PLANES Gee Bee Instruction Manual page 26

18. Repeat steps 7 - 17 to make a second, matching pushrod.
19. Install a clevis and silicone clevis keeper to the
threaded end of the wire the same as was done with the ailerons.
20. Insert the end of the pushrod wire with the clevis
into the fuselage and out through the most forward of the
two pushrod exit holes.
21. Install a control horn onto the bottom of the
elevator with two #2 x 1/2" [13mm] sheet metal screws
following the same procedure used for the ailerons. Be sure
the control horn is aligned with the pushrod and is on the
hardwood plate in the bottom of the elevator.
22. Repeat steps 19 - 21 for the opposite elevator.
23. Center both elevators and the elevator servos. The
elevator servos are located in the lower servo bays on both
sides of the fuselage. Attach the pushrods to the elevator
servos using nylon Faslinks following the same procedure
used for the ailerons.
24. From the remaining .074 x 17-1/2" [444mm] wire cut
a 6-1/2" [165mm] long rod threaded on one end.
25. On the remaining dowel measure up 1" [25mm] at
both ends of the dowel and make a mark. On the mark, drill
a 5/64" [2mm] hole through the dowel on both ends.
26. From the ends of the dowel to the holes make grooves.
27. On the non-threaded end of the 6-1/2" [165mm] wire
make a 90 degree bend 1/4" [6mm] from the end of the wire.
28. Insert the wire into the hole in the dowel. Glue the
wire to the groove with a small amount of medium CA.
29. Locate the remaining 2-3/8" [60mm] long pieces of heat
shrink tubing. Cut it in half. Slide one piece over the wire and
the dowel and shrink the tubing tightly to the dowel and wire.
30. From the leftover .074 x 17-1/2" [444mm] wire cut an
8" [203mm] long wire. Make a 90 degree bend 1/4" [6mm]
from the end of the wire. Insert the wire into the hole in the
dowel. Glue the wire to the groove with a small amount of
medium CA. After the glue has cured, insert and heat the
final piece of heat shrink tubing to the end of the dowel.
31. Install a clevis and silicone clevis keeper to the threaded
end of the wire the same as was done with the elevators.
32. Insert the end of the pushrod wire with the clevis into
the fuselage and out through the remaining pushrod exit
hole on the left side of the fuselage.
33. Install a control horn onto the left side of the rudder.
When placing the control horn it must be aligned with the
rudder pushrod wire and be aligned with the plywood plate
located under the fiberglass skin of the rudder. If you press
lightly on the fiberglass on the left side of the rudder you can
feel where the plate is because the fiberglass will be
noticeably stiffer in that area. When placing the control horn
it will have to be set back from the leading edge of the
rudder 1/8" [3mm]. When satisfied with the placement mark
the mounting hole locations for the control horn. Drill a 1/16"
[1.6mm] hole through both marks. Insert and then remove a
#2 x 1/2" [13mm] sheet metal screw through each hole.
Apply a couple of small drops of thin CA into the holes. After
the glue has cured install a large nylon control horn to the
rudder with the two #2 sheet metal screws.
