RECEIVER POWER SYSTEM REQUIREMENTS

Inadequate power systems that do not provide the necessary

minimum voltage to the receiver during ﬂ ight have become the

number one cause of in-ﬂ ight 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 AR8000 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 AR8000 features QuickConnect technology with Brownout

Detection.

• Should an interruption of power occur (brownout), the system

will reconnect immediately when power is restored.

• The LED on the receiver will ﬂ ash 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 Technology 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 ﬂ y safely through most short duration power interruptions.

However, you must correct the cause of these interruptions before

your next ﬂ ight to prevent a crash.

CAUTION: If a brownout occurs in ﬂ ight, determine the

cause of the brownout and correct it before attempting

to ﬂ y again.

EU versions of the DX7 are not compatible with DSM2 receivers.

Make sure all receivers are DSMX compatible.
