Flight Log (SPM9540 Optional)
The Flight Log is compatible with the AR9300. 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 AR9300. 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
Note:
– – – (three dashed lines) will appear if the antenna is not attached
Antenna fades
—represents the loss of a bit of information on that specific antenna.
In a carbon aircraft it’s not uncommon to have antenna fades maxed out. This is due to the fact that
individual antennas may be blocked at times during flight by carbon structure. What’s important is that
at least two antennas are receiving good information at all times.
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 in a five minute flight. 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 evaluate the system, moving the antennas to different locations and/or
checking to be sure the transmitter and receivers are all working correctly.
Note:
The Flight Log can be plugged in, attached and left in the model using double-sided tape.
Mounting the Flight Log conveniently inside the fusalage is recommended.
Tips on Using Spektrum 2.4GHz
ModelMatch
™
Some Spektrum and JR transmitters offer a patent pending feature called ModelMatch. ModelMatch prevents
the possibility of operating a model using the wrong model memory, potentially preventing a crash. With
ModelMatch 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 on screen.
Note
: 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.
While your DSM equipped 2.4GHz system is intuitive to operate, functioning nearly identically to 72MHz
systems, following are a few common questions from customers.
1. Q: Which do I turn on first, the transmitter or the receiver?
A:
If the receiver is turned on first
—no servo outputs are present so all servos remain in their position
and if an Electronic Speed Control is being used, it won’t arm. When the transmitter is then turned on
the transmitter scans the 2.4GHz band and acquires two open channels. Then the receiver that was
previously bound to the transmitter scans the band and finds the GUID (Globally Unique Identifier
code) stored during binding. The system then connects and operates normally.
If the transmitter is turned on first
—the transmitter scans the 2.4GHz band and acquires two open
channels. The receiver scans the 2.4GHz band looking for the previously stored GUID and when it
locates the specific GUID code and confirms uncorrupted repeatable packet information, the system
connects and normal operation takes place. Typically this takes 2 to 6 seconds.
2. Q: Sometimes the system takes longer to connect and sometimes it doesn’t connect at all?
A: In order for the system to connect (after the receiver is bound) the receiver must receive a large number
of consecutive uninterrupted perfect packets from the transmitter in order to connect. This process is
purposely critical of the environment ensuring that it’s safe to fly when the system does connect. If the
transmitter is too close to the receiver (less than 4 ft.) or if the transmitter is located near metal objects
(metal Tx case, the bed of a truck, the top of a metal work bench, etc.) connection will take longer and
in some cases connection will not occur as the system is receiving reflected 2.4GHz energy from itself
and is interpreting this as unfriendly noise. Moving the system away from metal objects or moving the
transmitter away from the receiver and powering the system again will cause a connection to occur.
This only happens during the initial connection. Once connected the system is locked in and should a
loss of signal occur (failsafe) the system connects immediately (4ms) when signal is regained.
3. Q: I’ve heard that the DSM system is less tolerant of low voltage. Is that correct?
A: All DSM receivers have an operational voltage range of 3.5 to 9.6 volts. With most systems this
is not a problem as in fact most servos cease to operate at around 3.8 volts. When using multiple
high-current draw servos with a single or inadequate battery/power source, heavy momentary
loads can cause the voltage to dip below this 3.5-volt threshold thus causing the entire system
(servos and receiver) to brown out. When the voltage drops below the low voltage threshold
(3.5 volts), the DSM receiver must reboot (go through the startup process of scanning the band
and finding the transmitter) and this can take several seconds. Please read the receiver power
requirement section as this explains how to test for and prevent this occurrence.
4. Q: Sometimes my receiver loses its bind and won’t connect requiring rebinding.
What happens if the bind is lost in flight?
A: The receiver will never lose its bind unless it’s instructed to. It’s important to understand that
during the binding process the receiver not only learns the GUID (code) of the transmitter but
the transmitter learns and stores the type of receiver that it’s bound to. If the transmitter is placed
into bind mode, the transmitter looks for the binding protocol signal from a receiver. If no signal
is present, the transmitter no longer has the correct information to connect to a specific receiver
and in essence the transmitter has been “unbound” from the receiver. We’ve had several DX7
customers that use transmitter stands or trays that unknowingly depress the bind button and the
system is then turned on losing the necessary information to allow the connection to take place.
We’ve also had DX7 customers that didn’t fully understand the range test process and pushed the
bind button before turning on the transmitter also causing the system to “lose its bind.”
Age Recommendation:

After Connection
• When the transmitter is turned on and after the receiver connects to the transmitter, normal control
of all channels occurs.
• After the system makes a connection, if loss of signal occurs Preset Failsafe drives all servos to their
preset failsafe positions set during binding.
Receiver Power System Requirements
Inadequate power systems that are unable to provide the necessary minimum voltage to the receiver
during flight have become the number one cause of 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 AR9300 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. small or old battery that may not support high-
current draw, etc.), it is recommended that a voltmeter be used to perform the following tests.
Note:
The Spektrum Flight Log (SPM9540) is the perfect tool to perform the test below.
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.
Note:
The latest generations of Nickel-Metal Hydride batteries incorporate a new chemistry
mandated to be more environmentally friendly. These batteries when charged with peak detection
fast chargers have tendencies to false peak (not fully charge) repeatedly. These include all brands
of NiMH batteries. If using NiMH packs, be especially cautious when charging, making absolutely
sure that the battery is fully charged. It is recommended to use a charger that can display total charge
capacity. Note the number of mAh put into a discharged pack to verify it has been charged to full
capacity.
QuickConnect
™
With Brownout Detection
Your AR9300 features QuickConnect with Brownout Detection.
• Should an interruption of power occur (brownout), the system will reconnect immediately when
power is restored (QuickConnect).
• The LED on the receiver will flash slowly indicating a power interruption (brownout) has occurred.
• Brownouts can be caused by an inadequate power supply (weak battery or regulator), a loose
connector, a bad switch, an inadequate BEC when using an electronic speed controller, etc.
• Brownouts occur when the receiver voltage drops below 3.5 volts thus interrupting control as the
servos and receiver require a minimum of 3.5 volts to operate.
How QuickConnect With Brownout Detection Works
• When the receiver voltage drops below 3.5 volts the system drops out (ceases to operate).
• When power is restored the receiver immediately attempts to reconnect to the last two frequencies
that it was connected to.
• If the two frequencies are present (the transmitter was left on), the system reconnects typically in
about 4/100 of a second.
QuickConnect with Brownout Detection is designed to allow you to fly safely through most short-
duration power interruptions; however, the root cause of these interruptions must be corrected before
the next flight to prevent catastrophic safety issues.
Note:
If a brownout occurs in flight it is vital that the cause of the brownout be determined and corrected.
