2. Slide the pushrods up through the slots in the
fuselage boom.
3/8" [ 8 -10 mm]
❏
3. Trim two servo arms down to holes 3/8" [8mm – 10mm]
from center and drill out the holes with a #55 (.052") drill.
Connect the pushrods to the servo horns and temporarily to
the screw-lock connectors on the rudder and elevator. Then
fi t the servo arms on the servos.
❏
4. Connect the ESC, servos and two 3" [75mm] servo
extensions to the aileron channels in your receiver.
❏
5. Mount the receiver in the fuselage with 1/8" [3mm]
double-sided foam mounting tape and tuck all excess wiring
neatly out of the way.
❏
6. Turn on the transmitter and connect a battery to the
ESC so you can operate the servos with your radio. Position
the servos laterally on the servo tray so the pushrods move
smoothly and do not interfere with the receiver or anything
else. Drill 1/16" [1.6mm] holes through the servo tray for the
mounting screws and temporarily mount the servos. Remove
the screws, harden the screw holes with thin CA, and allow
to harden. Then, mount the servos with the screws.
❏
7. With the servos and elevator and rudder centered (and
the radio system still on), lock the pushrods to the screw-lock
connectors with 3mm screws and a drop of threadlocker.
FINAL ASSEMBLY
Set the Control Throws
Measure the control throws at the widest part of the elevator,
ailerons and rudder. If necessary, use the programming
in your radio and/or reposition the pushrods on the servo
arms to achieve the specifi ed throws in the following chart.
(Moving the pushrods out on the servo arms will provide
more throw. Moving the pushrods in on the servo arms will
provide less throw.)
