screw-lock connectors and tighten the screws. Test
the operation of the throttle with your radio system
confi rming that the servo properly opens and closes
the carb. Make any adjustments necessary.
❏
3. Install the rudder and elevator servos into the
servo bays with the servo splines facing forward.
❏
4. Install a servo arm onto the rudder servo and
enlarge the outer hole of the arm with a 5/64" [2mm]
drill bit. With the rudder servo and rudder centered,
mark the rudder pushrod where it crosses the outer
hole of the servo arm. Make a 90° bend at the mark,
cut off the excess pushrod 1/4" [6mm] beyond the
bend and connect the pushrod to the servo arm and
secure it with a nylon FasLink.
❏
5. Cut a FasLink to 11/16" [17.5mm] long.
❏
6. Install a servo arm onto the elevator servo. As you
did with the rudder pushrod, center the right elevator
and make a bend in the pushrod where it crosses the
outer hole of the elevator servo arm. Center the left
elevator and make a mark on the pushrod 5/8" [16mm]
aft of the outer hole of the servo arm. Cut off the excess
pushrod at your mark.
❏
7. Loosely thread a 6-32 x 1/4" [6mm] SHCS into
two 5/32" [4mm] wheel collars with threadlocking
compound. Fit the wheel collars over both pushrod
ends. Connect the left elevator pushrod to the servo
arm and secure it with the shortened FasLink. Slide
both wheel collars just behind the FasLink, view the
plane from behind and confi rm that both elevator halves
are parallel, and
thoroughly tighten the screws in the
wheel collars. Test the operation of the elevator servo
with your radio. Make any fi ne adjustments with the
clevises to bring the elevator halves perfectly parallel
with each other.
❏
8. Make a hook and loop strap by cutting the
included material to a length that will wrap around your
receiver pack and then overlap the mating ends by
approximately 1" [25mm]. Cut a piece of foam rubber
(not included) to match your pack. Secure the pack to
the receiver tray with the strap.
