Recommended Power System Test Guidelines
If you are using a questionable power system, (e.g. a small or old battery,
an ESC that may not have a BEC that will support high-current draw, etc.),
perform the following test with a voltmeter.
The Hangar 9
® Digital Servo & Rx Current Meter (HAN172) or the Spektrum
Flight Log (SPM9540) work well for this test.
Connect the voltmeter to 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.
QuickConnect ™ Technology with Brownout Detection (DSM2 Only)
Your AR610 features QuickConnect technology 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, bad switch, inadequate BEC when using
an electronic speed controller, etc.
• Brownouts occur when the receiver voltage drops below 3.5 volts. This
interrupts 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 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, you must correct
the cause of these interruptions before your next flight to prevent a crash.
CAUTION: If a brownout occurs in flight, determine the cause
of the brownout and correct it before attempting to fly again.
Flight Log (SPM9540 Optional)
The Flight Log is compatible with the AR610. The Flight Log displays overall
RF link performance as well as the individual internal and external receiver
link data. Additionally, it also displays receiver voltage.
