9. Installing the rudder servo in the tray is very similar to
the way the elevator servo was installed in the tray. Locate
the rudder pushrod and slide it down the rudder pushrod
guide, as shown.
❏
10. The position of the pushrod guide exit is easily found
by lightly pushing on the rudder pushrod. Trim the covering
from around the pushrod guide exit. Center the rudder and
mark where the rudder pushrod overlaps the rudder.
❏
11. Measure a second mark 5/16" [8mm] from the hinge
line, as shown. Using a 5/32" [3.6mm] drill bit, drill a hole
through the rudder at point where the two marks intersect.
Slide the 6-32 x 2" [51mm] rod through the hole and center
it. Apply a drop of thread locker to each side of the bolt and
secure it with the two 6-32 nuts and washers.
❏
12. With the rod secure, install a nylon swivel to the end of
the rod as shown. Install a clevis and clevis keeper to the end
of the pushrod and slide the pushrod into the pushrod guide.
Hook the clevis onto the nylon swivel, but do not snap it shut.
❏
13. Place the rudder servo into the mounting tray. Mark the
mounting holes and, using a 1/16" [1.6mm] drill bit, drill pilot
holes for the mounting screws. Install the servo screws and
remove them. Place two drops of CA in each mounting hole.
Once the CA has cured, install the servo using the hardware
provided with the servo.
❏
14. Center the servo and the rudder. Mark the location
where the rudder pushrod intersects the servo arm. Make a
90° bend in the pushrod at the mark. Enlarge the servo horn
hole using a 5/64" [2mm] drill bit. Place the bend through the
servo hole, slide the FasLink in place, and trim off the excess
pushrod. If the rudder is no longer straight when the rudder
servo is centered, adjust by rotating the clevis as required.
Once the rudder is straight, snap the clevis shut and slide
the silicone clevis retainer over the clevis.
❏
15. There is a cooling air exit provided in the bottom of
the airframe just in front of the battery tray. Cut the covering
away from this section to provide cooling for the battery,
ESC, and motor.
