INSTALLING THE AR631 RECEIVER
1. Mount the receiver using double-sided servo tape. The receiver may be
mounted upright, upside down or on its side, but it should be square with
the fuselage in its mounting position. The receiver cannot be mounted at an
odd angle.
TIP: For SAFE setups, install the receiver as close to the center of gravity of
the aircraft as practical.
2. Connect the servos to their respective ports on the receiver using the chart
below.
CAUTION: Incorrect installation of the receiver could cause a crash.
Always perform a control surface check and AS3X control surface
response test before flying a new setup, or after any setup changes.

TRANSMITTER AND RECEIVER BINDING
Programming the AR631 receiver requires a Spektrum
™
DSM2
®
/DSMX

compatible transmitter with Forward Programming. Forward programming is
only available in DSMX.
BINDING
The AR631 receiver must be bound to your 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. Push and hold the bind button on the receiver while turning the receiver on.
Release the bind button once the orange LED starts to flash continuously,
indicating the receiver is in bind mode.
TIP: It is still possible to use a bind plug in the bind port if desired. This
can come in handy if the receiver needs to be mounted in a location that is
difficult to access, in which case a servo extension may be used for binding.
If using a bind plug, remove after binding to prevent the system from
entering bind mode the next time the power is turned on.
2. Put your transmitter in bind mode.
3. The bind process is complete when the orange LED on the receiver is solid.
IMPORTANT: When using Y-harness or servo extensions with Spektrum equi-
pment, do not use reversing harnesses. Using reversing Y-harnesses or servo
extensions may cause servos to operate erratically or not function at all.
