6. Position the control horn on the rudder as shown in
the sketch and on the plan. Use a ballpoint pen to mark the
location of the control horn mounting holes and drill 3/32"
holes at the marks. Temporarily mount the control horn to
the rudder with the backing plate and 2-56 x 5/8" screws.
❏
7. Position the rudder servo in the left side of the servo
tray as shown on the plans, using a long servo arm
included with your radio to position the servo so that the
end of the servo arm lines up with the pushrod. Mount the
servo. Note: Be sure the servo is positioned as shown with
the servo shaft toward the aft end of the fuselage to allow
clearance when the wing is attached.
❏
8. Neutralize the rudder (clamping the counterbalancer
to the fin, using balsa pads to keep from damaging the
rudder, works well) and be sure the servo arm is
perpendicular to the servo case. Cut the pushrod off 1/2"
behind the servo arm. Slide a solder clevis onto the
pushrod at the rudder servo. Attach the clevis to the outer
hole on the servo arm and mark the pushrod with a marker
at the aft edge of the clevis. Note: Leave the clevis and
pushrod installed until after you mount the elevator servos
to ensure proper clearance.
❏
9. Fit the elevators to the stabilizer, using the hinges to
hold in place. Do not glue. Note: If you wish to use twin
elevator servos, you will need to adjust the next few steps
accordingly to make them fit and mount the clevises, etc. If
you choose twin elevator servos, a computer radio with
appropriate mixing functions is REQUIRED, as the servo
arms must be mounted both facing inboard for the
pushrods to function properly.
❏
10. Thread a clevis onto one end of each 35" pushrod
wire (threaded on both ends) for the elevator pushrods.
Slide each pushrod through the elevator pushrod guide
tubes, which are the upper guide tubes on each side of the
fuselage. Remove the backing plates from two nylon
control horns and connect the horns to the clevises in the
outer holes. Position and temporarily mount the elevator
control horns as you did the rudder control horn.
❏
11. Position the elevator servo in the servo tray as
shown on the plans, using a medium servo arm included in
your radio to position the servo so that the end of the servo
arm lines up centered between the two pushrods. Mount
the servo. Note: Be sure the servo is positioned as shown
with the servo arm toward the aft end of the fuselage to
allow clearance when the wing is attached.
❏
12. Neutralize both elevators (clamping them to the stab
and using balsa pads to keep from damaging them) and be
sure the servo arm is perpendicular to the servo case. Cut
one pushrod 1/2" behind the servo arm; cut the second
pushrod off 1" behind the servo arm. Save the two leftover
pieces for the ailerons. Note: The two elevator pushrods
will not be joined until final assembly, after the model is
covered.
❏
13. Slide the solder clevis onto the longer pushrod, clip
the solder clevis onto the servo, and mark as you did the
rudder pushrod.
❏
14. Remove all three pushrods and both solder clevises
from the aircraft. Position the nylon bushings, equally
spaced, onto the wire pushrods. Note: The longest pushrod
