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 AR8010T has a minimum operational voltage of 3.5 volts; test
the power system 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 and Receiver 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)
The AR8010T 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 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 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 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.
EU versions of the DX8e are not compatible with DSM2®receivers.
Make sure all receivers are DSMX®compatible.
European Union Receiver Requirements

13SPEKTRUM DX8e • TRANSMITTER INSTRUCTION MANUAL
EN
You establish failsafe positions when you bind your transmitter
and receiver. If the radio signal connection is lost between the
transmitter and receiver, the receiver immediately moves the
aircraft control surfaces to the failsafe positions. If you assign the
receiver THRO channel to a transmitter channel other than throttle,
we recommend using Preset failsafe with the throttle in the low
position.
NOTICE: Failsafe features vary according to receiver. Always
consult the receiver instruction manual for failsafe features.
Before flight, ALWAYS confirm the failsafe functions as you would
expect.
SmartSafe™ Failsafe
SmartSafe failsafe is a technology that only acts on the throttle
channel and offers the following benefits:
• Prevents electric motors from operating when the receiver
power is on and the transmitter power is off.
• Prevents the speed controller from arming until the throttle is
moved to the low throttle position.
• Powers off an electric motor and reduces gas/glow engines to
idle if signal is lost.
To Program SmartSafe, move the throttle to the low or off position
before putting the transmitter into bind mode.
To Test the SmartSafe failsafe:
1. Power the transmitter and receiver on.
2. Power off the transmitter. The throttle should immediately
move to the failsafe position.
CAUTION: Make sure the aircraft is fully restrained on
the ground. If the failsafe is not set correctly, your aircraft
might advance to mid or full throttle.
Hold Last Command
The Hold Last Command failsafe maintains the last command on
all channels except throttle. If the radio signal is lost, the aircraft
maintains the commanded control inputs until the receiver regains
signal.
To program Hold Last Command, follow the provided binding
instructions in this manual.
To Test Hold Last Command:
1. Power on the transmitter and receiver.
2. Move one of the control sticks to the desired Hold Last
Command position and hold the input.
3. While holding the control input (for example, a small amount
of rudder) power off the transmitter. The rudder should
maintain the input command.
CAUTION: Make sure the aircraft is fully restrained on
the ground. If the failsafe is not set correctly, the aircraft
throttle might advance to mid or full throttle.
Preset Failsafe
The Preset failsafe moves all channels to their programmed
failsafe positions.
We recommend using Preset failsafe to deploy spoilers on sail-
planes to prevent a flyaway if the radio signal is lost.
To program Preset failsafe:
1. Insert the bind plug in the bind port on the receiver and power
on the receiver.
2. Remove the bind plug when the orange LED on the main
receiver and all attached remote receivers flash rapidly. The
orange receiver LEDs will continue flashing.
3. Move the transmitter control sticks and switches to the
desired Preset failsafe position. Power the transmitter on.
4. Failsafe programming is complete when the orange LEDs on
the transmitter and all receivers turn solid.
CAUTION: Make sure the aircraft is fully restrained on
the ground. If the failsafe is not set correctly, the aircraft
throttle might advance to mid or full throttle.
PROGRAMMING FAILSAFE POSITIONS
IMPORTANT: Not all receivers support Preset Failsafe. Consult
your receiver manual for more information.
