AR9310 User Guide
The Spektrum AR9310 9-channel receiver is designed for carbon fiber
aircraft installations. Carbon Fiber can create an RF shielding effect that
can significantly reduce radio range when using conventional receivers and
antennas. The AR9310 features an antenna design that overcomes RF issues in
these critical environments.
The AR9310 receiver features DSMX® technology and is compatible with all
Spektrum™ and JR® aircraft radios that support DSM2/DSMX technology
including Spektrum DX7, DX6i, DX5e, JR 12X, JR X9303, and Spektrum
Module Systems.
NOTICE: The AR9310 receiver is not compatible with the Spektrum DX6
parkflyer transmitter.

Receiver Installation in Aircraft
Airplanes with significant carbon fiber construction can create an RF shielding
effect, reducing range. The AR9310 is designed to overcome these critical RF
issues in carbon airplanes by outfitting the aircraft with external antennas when
necessary at specific points that will ensure secure RF coverage from all angles
of the aircraft.

Feeder Antennas
The AR9310 incorporates feeder antennas, which are designed to be easily
mounted through the fuselage in carbon airplanes. The main receiver has two
8-inch feeder antennas and the remote receiver has one. Each feeder antenna
includes a coaxial portion (which can be thought of as an extension) and an
exposed 31mm tip antenna. The last 31mm is the active portion of the antenna.

Step 1. Identifying the Types of Carbon Aircraft
While some sailplanes are full carbon construction, most only use carbon in
areas that require extra strength. Many of the latest sailplanes are constructed
with 2.4GHz-friendly fuselages meaning that the forward section of the
fuselage is constructed from non-conductive materials like fiberglass and
Kevlar that don’t affect the RF signal. The first step in a proper installation is
identifying the type of aircraft which will fall into one of three categories on the
following page.
