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 AR8000 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.
