Installation
Installation (continued)
• Mount the Receiver unit in the position recommended by the
helicopter manufacturer. Foam or thick double-sided tape is
recommended to isolate the receiver from vibration.
• Mount the switch and insert the switch plug into the port in the
main unit marked SWITCH. Note: The AR7100/AR7100R uses a
specifically designed switch. Conventionally wired switches are not
compatible with the AR7100.
• Using the battery capacity guidelines select the battery system that
best fits your application and install the battery in your heli. Connect
the battery to the receiver’s EC3 connector. Spektrum batteries
are pre-wired with an EC3 connector and plug directly in. If using
another brand of battery it will be necessary to solder EC3 connectors
to the battery leads.
• Using double-sided foam tape and tie wrap, mount a minimum of
1 and up to 2 remote receivers in your aircraft and plug them into the
receiver ports. NOTE: It’s necessary that one receiver be plugged into
port B or R in order to operate. The receiver should be mounted at
least 2” away from the main receiver with the antennas perpendicular.
• If using the RevLimit Limiter (AR7100R only) mount the rpm
sensor and bracket to the backplate under two backplate screws of
your engine as shown.
Note: Threadlock must be used on the screws. The rpm sensor
bracket is adjustable for 50-size or 90-size engines by extending or
retracting the rpm sensor and fastening the screw in place.
• Plug the servo leads and rpm sensor into the appropriate ports in
the receiver.
• You’re now ready to bind the system.
Note: In order for the system to operate one remote receiver must be
plugged into receiver port B or R.
Connections
Note: The throttle and gear channels have two outputs. Output 1 is
unregulated and the pack voltage is provided at this port. Throttle and
Gear outputs 2 are regulated to 5.2 volts when a throttle servo and
gyro are used that are not compatible with high voltage. (Most gyros
require less than 6 volts.)
