have significant carbon or conductive structures. It is recommended to use either the
AR6250 or AR9300 receivers for carbon fuselage applications.
Note: When used as a single receiver it is recommended that an appropriate model type is
used. Recommended types of aircraft: 250- to 500-size electric helicopters,
parkflyer and sport aircraft.

Patented MultiLink ™ Receiver Technology
The AR7600 incorporates dual receivers, offering the security of dual path RF redundancy. An
internal receiver is located on the main printed circuit board, while a second external receiver
is attached to the main board with a 6-inch extension. By locating these receivers in slightly
different locations in the aircraft, each receiver is exposed to its own RF environment, greatly
improving path diversity (the ability for the receiver to see the signal in all conditions).
Antenna Polarization
For optimum RF link performance it's important that the antennas be mounted in an orientation
that allows for the best possible signal reception when the aircraft is in all possible attitudes and
positions. This is known as antenna polarization. The antennas should be oriented perpendicular
to each other; typically one vertical and one horizontal (see Receiver Installation). The remote
receiver's antenna should be mounted in a position perpendicular at least 2 inches away from
the main receiver's antenna using double-sided foam tape.

Receiver Installation

In gas and glow aircraft install the main receiver using the same method you would use to install
a conventional receiver in your aircraft. Typically, wrap the main receiver in protective foam and
fasten it in place using rubber bands or hook and loop straps.
Alternately, in electric airplanes or helicopters, it's acceptable to use thick double-sided foam tape
to fasten the main receiver in place.
Mounting the remote receiver in a slightly different location, even just inches away from the
primary receiver, gives tremendous improvements in path diversity. Essentially, each receiver
sees a different RF environment and this is key to maintaining a solid RF link, even in aircraft that
have substantial conductive materials (e.g. larger gas engines, carbon fiber, pipes, etc.), which
can weaken the signal.
Using servo tape, mount the remote receiver keeping the remote antennas at least 2 inches away
from the primary antenna. Ideally, the antennas will be oriented perpendicularly to each other. In
airplanes, we've found it best to mount the primary receiver in the center of the fuselage on the
servo tray and to mount the remote receiver to the side of the fuselage or in the turtle deck.
In helicopters, there is generally enough room on the servo tray to achieve the necessary separation.
If necessary a mount can be fashioned using clear plastic to mount the external receiver.
Important: Y-Harnesses and Servo Extensions
When using Y-harnesses or servo extensions it's important to use standard non-amplified
Y-harnesses and servo extensions as this can/will cause the servos to operate erratically or not
function at all. Amplified Y-harnesses were developed several years ago to boost the signal for
some older PCM systems and should not be used with Spektrum equipment. Note that when
converting existing models to Spektrum be certain that all amplified Y-harnesses and or servo
extensions are replaced with conventional non-amplified versions.

Binding

The receiver must be bound to the transmitter before it will operate. Binding is the process of
teaching the receiver the specific code of the transmitter so it will only connect to that specific
transmitter.
1. To bind an AR7600 to a DSM2 transmitter, insert the bind plug in the BATT/BIND port on the
receiver.
Note: To bind an aircraft with an electronic speed controller that powers the receiver through
the throttle channel (ESC/BEC), insert the bind plug into the BATT/BIND port in the
receiver and the throttle lead into the throttle (THRO) port. Proceed to Step #2.
2. Power the receiver. Note that the LED on the receiver should be flashing, indicating that the
receiver is in bind mode and ready to be bound to the transmitter.
3. Move the sticks and switches on the transmitter to the desired failsafe positions (low throttle
and neutral control positions).
4. Follow the procedures of your specific transmitter to enter Bind Mode, the system will
connect within a few seconds. Once connected, the LED on the receiver will go solid
indicating the system is connected.
5. Remove the bind plug from the BATT/BIND port on the receiver before you power off the
transmitter and store it in a convenient place.
6. After you've set up your model, it's important to rebind the system so the true low throttle and
neutral control surface positions are set.
IMPORTANT: Remove the bind plug to prevent the system from entering bind mode the next
time the power is turned on.
