Install the Radio
❏
1. If necessary, enlarge the cutout in the servo tray to
fi t your servos. Then install the servos in the tray, but don’t
screw them down yet.
❏
2. Cut the unused arms from your servo arms and place
them on your servos. Center the servos and control surfaces.
Mark the elevator and rudder pushrods where they cross the
holes in the servo arms.
Refer to this photo while completing servo hookup.
❏
3. Disconnect the clevises from the horns on the elevator
and rudder and remove the pushrods from the fuselage. Make
a 90-degree bend in each pushrod at the marks. Fit each
pushrod to a servo arm, install a 90-degree pushrod keeper
and cut off the excess wire.
❏
4. Remove the clevises from the back of the pushrods so
they can be reinstalled into the guide tubes in the fuselage.
Install the pushrods and thread the clevises back on.
❏
5. Adjust the length of the pushrods as necessary by
threading the clevises in or out, then reinstall the servo arms
onto the servos.
❏
6. Cut the nose steering pushrod to the correct length and
bend it as necessary to connect the rudder servo. Connect
the pushrod to the servo arm using a screw-lock connector,
an M3 set screw and a retainer.
❏
7. Install the throttle servo (if used) and use another
screw-lock connector to connect the throttle pushrod to
the throttle servo.
❏
8. Now that all the pushrods are connected, drill 1/16"
[1.6mm] holes in the servo tray for the servo screws. Mount
the servos with the screws that came with them.
❏
9. Mount the receiver and receiver battery (if used) with
remaining hook-and-loop strap and R/C foam rubber. Mount
an on/off switch (also if used). The image in this step is for a
glow setup. For a brushless motor setup, the receiver may
be mounted to the servo tray over the location for the glow
throttle servo or to the side of the fuselage in the same area.
❏
10. Plug a Y-harness or servo extensions into your receiver
to connect to the ailerons through the bottom of the fuselage
for connecting to the servo leads from the wing.
PREPARE THE MODEL FOR FLIGHT
Set the Control Throws
CAUTION:
If you have installed a brushless motor, remove
the propeller before turning on the radio and checking the
throws on the workbench.
In addition to the C.G., the control throws also have a major
effect on how the model fl ies and whether or not your fi rst fl ight
will be successful. Do not skip this important step and make
sure the throws are within the specifi ed range. If necessary
use programming in your transmitter and/or change the
locations of the pushrods in the servo arms and/or control
horns to adjust the throw.
