RECEIVER POWER SYSTEM REQUIREMENTS
Inadequate power systems that do not 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ESC’scapabilitytodelivercurrenttothereceiverinelectricaircraft
• Theswitchharness,batteryleads,servoleads,regulatorsetc.
The AR610 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 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.

QuickConnect with Brownout Detection is designed to allow you to fly safely through most short duration power interruptions. However,

CAUTION: If a brownout occurs in flight, determine the cause of the brownout and correct it before attempting to fly again.
