Installation

• Mount the Receiver unit in the position recommended by the helicopter manu-

facturer. 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 AR7110/AR7110R uses a speciﬁcally designed switch.

Conventionally wired switches are not compatible with the AR7110.

• Using the battery capacity guidelines select the battery system that best ts

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 conne-

ctor 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 (AR7110R only) mount the rpm sensor and bracket

to the backplate under two backplate screws of your engine as shown.

IMPORTANT: Normally, the pickup is mounted touching the backplate of the

engine. If your system is not limiting RPM in ﬂight, re-position the sensor .5 to

1mm away from the back plate. This can be easily accomplished by loosening the

2-56 button head screw on the sensor mount, re-adjusting the position, and then

tightening. This should resolve the issue.

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.
