3. Establish the desired failsafe stick positions: normally low throttle and flight controls neutral.

4. Press and hold the bind button on the back of the transmitter while turning on the power switch.
The bind button should flash and within a few seconds the system should connect. The LED’s on the
receivers should go solid indicating the system has connected.

5. Remove the bind plug from the receiver and store it in a convenient place.
REMOVE BEFORE USE
6. After you’ve programmed your model, it’s important to rebind the system so the true low throttle and
neutral control surface positions are programmed.
Note: The AR7000 features DSM2 technology and is only compatible with DSM2 transmitters.
The AR7000 will not operate with the DX6 or Spektrum surface systems.

Flight Log—Optional for AR7000 Receiver
The Flight Log is compatible with AR7000 receivers. The Flight Log displays overall RF link performance as well
as the individual internal and external receiver link data. Additionally it displays receiver voltage.
Using the Flight Log
After a flight and before turning off the receiver or transmitter, plug the Flight Log into the Data port on the
AR7000 receiver. The screen will automatically display voltage e.g., 6v2= 6.2 volts.
Note: When the voltage reaches 4.8 volts or less, the screen will flash indicating low voltage.
Press the button to display the following information:
A - Antenna fades on internal antenna A
B - Antenna fades on internal antenna B
L - Antenna fades on the left external antenna
R - Antenna fades on the right external antenna
F - Frame loss
H - Holds
Antenna fades—represents the loss of a bit of information on that specific antenna.
Typically it’s normal to have as many as 50 to 100 antenna fades during a flight.
If any single antenna experiences over 500 fades in a single flight, the antenna should be repositioned in the
aircraft to optimize the RF link.
Frame loss—represents simultaneous antenna fades on all attached receivers. If the RF link is performing
optimally, frame losses per flight should be less than 20.
A hold occurs when 45 consecutive frame losses occur.
This takes about one second. If a hold occurs during a flight, it’s important to reevaluate the system, moving the
antennas to different locations and/or checking to be sure the transmitter and receivers are all working correctly.
Note: A servo extension can be used to allow the Flight Log to more conveniently be plugged
in without having to remove the aircraft’s hatch or canopy. On some models, the Flight Log can
be plugged in, attached and left on the model using double-sided tape. This is common with
helicopters, mounting the Flight Log conveniently to the side frame.
