Standard Range Testing
Before each flying session, and especially with a new model, it’s important to
perform a range check. All Spektrum aircraft transmitters incorporate a range
testing system, which reduces the output power allowing a range check.
Range Testing
1. With the model resting on the ground, stand 30 paces (approx. 90 feet/28
meters) away from the model.
2. Face the model with the transmitter in your normal flying position and put your
transmitter into range test mode. This causes reduced power output from the
transmitter.
3. You should have total control of the model in range test mode at 30 paces (90
feet/28 meters).
4. If control issues exist, call Horizon Product Support for further assistance.

Advanced Range Testing Using a Flight Log
The Standard Range Testing procedure is recommended for most sport aircraft. For
sophisticated aircraft that contain significant amounts of conductive materials (e.g.
turbine powered jets, some types of scale aircraft, aircraft with carbon fuselages,
etc.), the following advanced range check will confirm that all remote receivers are
operating optimally and that the installation (position of the receivers) is optimized
for the specific aircraft. This Advanced Range Check allows the RF performance
of each remote receiver to be evaluated and to optimize the locations of each
individual remote receiver.
Advanced Range Testing
1. Plug a Flight Log into the data port in the AR12120 and turn on the system (Tx
and Rx).
2. Advance the Flight Log until frame losses are displayed by pressing the button
on the Flight Log.
3. Have a helper hold your aircraft while observing the Flight Log data.
4. Standing 30 paces away from the model, face the model with the transmitter in
your normal flying position and put your transmitter into range test mode. This
causes reduced power output from the transmitter.
