typically vertical and horizontal and at different angles (see Receiver Installation

below). The remote receiver 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 Aircraft

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. The AR9010 requires at least one remote receiver to operate. Mounting

this remote receiver in a slightly different location, even just inches away

from the primary receivers, 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 antennas. 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. A second remote receiver can be added for additional

RF link security.

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 remote receiver.
