elevator pushrod wire you soldered the clevis to followed by
two 5/32" [4mm] wheel collars. Then, insert the wire into the
tube. Attach the clevis to the servo arm and slide the clevis
keeper over the clevis.
❏
9. On the threaded end of the wire, thread a 4-40 nut and
the clevis onto the wire. Slide a clevis keeper over the clevis.
Center the elevator servo and the right elevator. Adjust the
clevis as needed until the clevis pin is aligned with the hole
in the control horn. Attach the clevis to the control horn, and
then tighten the 4-40 nut against the clevis. Apply a drop of
threadlocker to the nut before tightening it against the clevis.
Slide the clevis keeper over the clevis.
❏
10. On the left elevator pushrod wire thread a 4-40 nut
and the clevis onto the wire. Slide a clevis keeper over the
clevis. Slide the wire into the fuselage, and then attach the
clevis to the control horn. Apply a drop of threadlocker to the
nut before tightening it against the clevis. Slide the clevis
keeper over the clevis.
❏
11. Bend the left elevator pushrod wire as shown. Cut off
the excess wire from the left pushrod and slide the wheel
collars over both of the pushrod wires. Center the servo and
center the left elevator. Install a 6-32 x 1/4" [6mm] SHCS into
each of the wheel collars, tightening them against the
pushrod wires. Be sure to use a drop of threadlocker on
each of the screws.
❏
12. Slide the remaining pushrod wire into the remaining
pushrod tube in the fuselage. Push it into the tube until it
touches the covering on the outside of the fuselage. Cut the
covering away to allow the wire to exit the fuselage side.
Remove the wire from the tube.
❏
13. Install a threaded metal clevis onto the threaded end
of the remaining pushrod wire approximately 20 turns.
❏
14. Connect a nylon control horn onto the clevis. Slide the
pushrod wire into the fuselage. Position the control horn on
the rudder, positioning it on the plywood plate the same way
you did with the elevators. Mark the location for the screw
holes. On the marks, drill through the plywood plate with a
1/16" [1.6mm] drill bit. Drill only through the plate, not
through the rudder! Secure the control horn to the rudder
with two #2 x 3/8" [9.5mm] SMS.
❏
15. Position the rudder servo in the servo tray (remember
if you are doing the electric motor installation with NiMH
batteries you should be installing this into the secondary
servo tray you installed) so that the servo arm is just above
the rudder pushrod wire.
❏
16. Using the same technique used for the elevator, install
a 4-40 solder clevis into the outer hole of the servo arm.
Center the rudder and center the servo. Make a mark on the
wire indicating where the wire needs to be cut. Remove the
clevis from the servo arm and remove the pushrod wire from
the fuselage.
❏
17. Cut the pushrod on the mark you made. Solder the clevis
to the wire using the same technique used for the elevator.
❏
18. Remove the threaded clevis from rudder pushrod
wire. Slide a silicone clevis keeper onto the rudder pushrod
wire, and then insert the pushrod wire back into the tube.
Attach the clevis to the servo arm and slide the clevis keeper
over the clevis.
