Binding Procedure
1. Insert the bind plug in the BND/DAT port on the receiver.
2. Connect the flight battery to the ESC. The H menu LED should be flashing, indicating the AR7200BX is in bind mode.
3. Move the throttle stick to the desired failsafe position (low throttle position in normal mode).
4. Power on the transmitter while holding the Trainer/Bind switch. Hold the Trainer/Bind switch until binding is complete. The system will connect within a few
seconds. Once connected, the H LED will turn off and the AR7200BX will start the initialization process.
5. When the initialization process is complete, menu LED H will turn OFF and the Status LED light will come ON solid BLUE.
6. Disconnect the flight battery and remove the bind plug from the AR7200BX. Store the bind plug in a convenient place.
WARNING:
You must move the throttle to the LOW/OFF position during
binding. Failure to do so may cause the rotor blades to spin and the heli-
copter to lift during the AR7200BX initialization, which could result in damage to
property and injury.
NOTICE:
Remove the bind plug to prevent the system from entering bind mode the
next time the power is turned on.
If you encounter problems, obey binding instructions and refer to transmitter
troubleshooting guide for other instructions. If needed, contact the appropriate
Horizon Product Support office.
The transmitter comes prebound to the model. If you need to rebind, follow the directions below.
Transmitter and Receiver Binding
Throttle Hold
Throttle hold only turns off the motor on an electric helicopter. You maintain pitch
and direction control.
The blades will spin if throttle hold is OFF. For safety, turn throttle hold ON any time
you need to touch the helicopter or check the direction controls.
Throttle hold is also used to turn off the motor if the helicopter is out of control, in
danger of crashing, or both.
Rudder
1. Power on the transmitter.
2. Turn TH HOLD ON and put transmitter in normal mode.
3. Connect the helicopter battery to the ESC.
NOTICE:
Do not allow the helicopter to move until the Status LED is solid blue and
all menu LEDs are OFF. The gyro will not operate correctly if the helicopter moves
before the Status LED is solid blue.
4. Move the rudder stick to the right. The
tail rotor blades move as shown. If they
do not move as shown, reverse the rudder
channel in the transmitter (refer to your
transmitter manual for instructions).
5. Release the rudder control. Manually turn
the helicopter nose to the left. The tail ro-
tor blades automatically move as shown.
If they do not move as shown, refer to the
AR7200BX manual for information on reversing the tail sensor direction
(Setup menu point F).
Cyclic
When using a flybarless rotor head, you are controlling rotational rates while the
AR7200BX controls the servos. You are not directly controlling the servos with the
transmitter.
It is normal for the swashplate to slowly move back to its original position
after a stick input and for the servos to not move at the same speed as your
control sticks.
1. Tilt the helicopter forward. The swashplate should tilt backward.
2. Tilt the helicopter backward. The swashplate should tilt forward.
3. Roll the helicopter left. The swashplate should roll right.
4. Roll the helicopter right. The swashplate should roll left.
5. If the swashplate does not move in the correct direction, you will need to
reverse the cyclic sensor direction. Refer to the AR7200BX manual for more
information (Setup menu point M).
Control Tests
CAUTION:
You must complete the Rudder and Cyclic tests prior to flight. Failure to complete the tests ensuring the sensor directions are not reversed can cause
the helicopter to crash, resulting in property damage and injury.
