in-flight failures. Some of the power system components that affect the ability
to properly deliver adequate power include:
• Receiver battery pack (number of cells, capacity, cell type, state of
charge)
• The switch harness, battery leads, servo leads, regulators, etc.
• The BEC used in the speed controller won’t support the current
required by the servos.
The AR6260 has a minimum operational voltage of 3.5 volts; it is highly
recommended the power system be tested per the guidelines below.
Recommended Power System Test Guidelines
If a questionable power system is being used (e.g. a small or old battery that
may not support high-current draw, etc.), it is recommended that a voltmeter
be used to perform the following test.
Tip: The Spektrum Flight Log (SPM9540) is the perfect tool to monitor voltage
in the test below. The Flight Log is not compatible with the AR6260 for
recording flight data.
Plug the Flight Log into an open channel port in the receiver and with the
system on, load the control surfaces (apply pressure with your hand) while
monitoring the voltage at the receiver. The voltage should remain above 4.8
volts even when all servos are heavily loaded.
CAUTION: When charging Ni-MH batteries, make sure the battery fully
charges. Ni-MH batteries charged with peak detection fast chargers
have a tendency to false peak (i.e. not fully charge), which
could lead to a crash.
ModelMatch
™
Technology
Some Spektrum and JR transmitters offer a feature called ModelMatch
technology that prevents the possibility of operating a model using the wrong
model memory, potentially preventing a crash. With ModelMatch technology,
each model memory has its own unique code (GUID) and, during the binding
process, the code is programmed into the receiver. Later, when the system is
turned on, the receiver will only connect to the transmitter if the corresponding
model memory is programmed onscreen.
IMPORTANT: If at any time you turn on the system and it fails to connect,
check to be sure the correct model memory is selected in the transmitter.
Please note that the Spektrum Aircraft Modules do not have ModelMatch
technology.
