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-harness 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 amplfied Y-harnesses and or servo

extensions are replaced with conventional non-amplified versions.

Binding

The AR7000 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.

To bind an AR7000 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.

Receiver Technology

The AR7000 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

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.

Move the sticks and switches on the transmitter to the desired failsafe positions (low throttle

and neutral control positions).

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.

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.

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.
