The DX8 is Spektrum's first aircraft system that incorporates integrated telemetry. The
transmitter's screen displays real-time telemetry including receiver battery voltage, flight log
data and signal quality. External sensors allow rpm, external voltage and temperature to be
displayed on screen in real time. Alarms can be programmed to warn of low battery, over
temperature, exceeded rpm and diminished RF signal strength. The DX8 offers sophisticated
programming to meet the demands of even the most experienced airplane and helicopter
pilots. An easy-to-use rolling selector combined with intuitive software makes setting up
models quick and easy. The DX8 is SD-card compatible allowing an infinite number of models
to be stored and transferred. Plus firmware updates can be downloaded from the
SPEKTRUMRC.com website providing the user with the latest software upgrades.

CHARGING YOUR TRANSMITTER
normally the default cutoff of 6.4 volts for LiPo is recommended.
The DX8 features a built-in multi-chemistry charger designed to charge 4-cell NiMH and 2-cell
LiPo batteries at a charge rate of 200mAh. The charge jack on the right side of the transmitter
is non-polarity-critical, allowing you to use any type of 12-volt supply to charge the battery
regardless of connector polarity. Using the included SPMB2000NMTX NiMH battery pack, you
should plug the included 12-volt AC to DC power supply in for 10 to 12 hours to fully charge
the battery.
A CAUTION: Never plug in a peak detection or fast charger into your DX8 as this could
damage the internal charge circuit. Use only a 12V DC source.
FR
EVl
With the transmitter power turned off, plug the included 12 volt power supply into a wall outlet.
Then plug the male charge plug into the charge jack. The blue LED on the front of the
transmitter will illuminate. When charging the optional SPMB4000LPTX, a full charge can take
up to 30hrs depending on the initial charge state of the battery. When charging a
LiPo, the blue light will turn off when the charge cycle is complete.
NIMH/LIPO BATTERY SUPPORT
The DX8 includes a rechargeable NiMH battery pack. A low battery alarm sounds when the
battery reaches 4.3 volts. Spektrum offers an optional 2-cell LiPo battery pack (SPMB4000LPTX)
for the DX8. LiPo batteries have a higher operational voltage and when switching to a 2-cell LiPo
battery in the transmitter, it is important to change the low battery alarm to the LiPo setting to
prevent over-discharging the pack. To Access and Change Battery Type
In the System Setting screen (see page 20 in your manual) rotate the roller to select NEXT at the
bottom right of the System setting screen. The following screen appears.

FAILSAFES
When you bind your transmitter, you are programming the receiver with failsafe
defaults. If connection is lost between the transmitter and receiver, the receiver
immediately operates in those preprogrammed default positions. Those positions
are failsafes. The AR8000 has three failsafes: SmartSafe Failsafe, Hold Last

The DX8 features
ModelMatch technology
that prevents operating a
model using the wrong
model memory. This
feature can prevent
stripped servo gears,
broken linkages and even a
crash due to attempting to
operate a model using the
wrong memory. HOW
ModelMatch Works Each
individual model memory
(30 in total) has its own
embedded code
transferred to the receiver
during the binding process.
The receiver actually learns
the specific model memory
selected during binding.
When bound, it operates
only when that model
memory is selected. If a
different model memory is
selected, the receiver won't
connect. At any time you
can reprogram the receiver
to operate with any other
model memory by
rebinding with the
transmitter programmed to
the desired model. Note:
When you change model
types (Heli to Acro or Acro
to Heli) all current
programming in the
selected model memory
will reset to the factory
default settings. All

Temperature, Voltage and Optional RPM Sensors
The TM1000 includes a temperature and external voltage sensors. Optional RPM sensors are
available for Gas/Glow and electric brushless models to monitor RPM.
Temperature Sensor
To monitor the temperature of most any component, secure the sensor on the object. It must
come into contact with the surface to get an accurate temperature reading. You can loop the
temperature sensor around the engine's cylinder head to assist in tuning an engine. To
monitor battery temperature, you can wrap the sensor around the battery. The mounting
position of the sensor, especially on gas or glow engines, will result in different temperature
readings. So it's important to experiment with different positions.
RPM (optional sensor sold separately)
Two RPM sensors are available: SPMA9569 for nitro and gas engines, SPMA9558 for
brushless electric motors.
12
SPEKTRUM DX8 • RADIO INSTRUCTION MANUAL
Installation
Insert the temperature sensor connector into the port labeled TEMP/VOLT. The temperature
sensor is now active and the actual temperature displays on screen.
Installation
Install the backplate sensor in the backplate. Install the connector into the RPM port in the
TM1000.
Testing

Telemetry
Turn the transmitter and receiver on and scroll to the RPM telemetry screen. Rotate the engine
rapidly and the RPM should register on the screen. The RED LED on the TM1000 indicates the
sensor is picking up properly. You may need to adjust the sensor's position to optimize the pickup.
Move the sensor closer or farther away until you have a reliable RPM pickup.
External voltage
External voltage telemetry is commonly used to monitor flight pack voltage or you can monitor
ignition batteries on gas engine equipped aircraft. You can set warnings to prevent overdischarging batteries.
Installation
Plug the connector of the voltage sensor into the TEMP/VOLT port in the Telemetry
module.
Attach the opposite ends of the voltage sensor (stripped wires) to the
voltage source you wish to monitor.
Note the polarity (Red = + positive /Black = - Negative).
Typically, you can solder the wires to the battery connector. At this point the
External voltage displays on the telemetry screen.
Note: A Y-harness is provided if you want to use temperature and voltage sensors
simultaneously.
Engine RpM Sensor
The optional engine RPM sensor mounts inside the backplate of aircraft engines. The sensor
picks up the crankpin as the engine rotates giving accurate RPM. Additionally, you can use this
sensor as an RPM pickup on any rotating gear/ collar or shaft that has a steel setscrew or other
12

In Inhibit you can use the transmitter as a slave only. However, the slave transmitter

Programmable Master
With Programmable Master you can program the transmitter to transfer any or all channels

individual channels (aileron only for example) while the trainer maintains control of all other
channels.
Note: When Programmable Master is selected for the master transmitter, all settings for

trim (throttle, aileron, elevator and rudder).
Typically, this is used when more than one
channel is used to operate a primary
control surface (dual rudder servos, etc.)
With trim include activated, the master
channel's trim affects the master and slave
channels.

The Tail Curve programming functions
nearly identically to the Throttle and Pitch
curve programming. You can assign four
separate Tail curves or a common Tail
curve to 2 or more flight modes. A graph
displays at the left side of the screen to
help you adjust the Tail curves. An Expo
function is available that smooths out the
curve.
Note: Only use tail curves when
the gyro is in the conventional gain
(non- heading hold) mode.

Purpose
This advisory outlines safety standards for operations of model aircraft. We encourage
voluntary compliance with these standards.
Background
Horizon reserves the right to change or modify this
warranty without notice and disclaims all other warranties,
express or implied.
Attention has been drawn to the increase in model aircraft operation. There is a need for added
caution when operating free flight and radio controlled craft in order to avoid creating a noise
nuisance or a potential hazard to full-scale aircraft and persons and/or property on the surface.
Operating Standards
Modelers generally are concerned with safety and exercise good judgment when flying model
aircraft. However, in the interest of safer skies, we encourage operators of radio controlled and
free flight models to comply with the following standards:
a.Exercise vigilance in locating full-scale aircraft (get help if possible) so as not to create a
collision hazard.
b.Select an
operating
site
sufficient
at
distance from populated
areas so you do not
create a noise problem
or a potential hazard.
c.Do not fly higher than

USING A FLIGHT LOG—OPTIONAL
The Flight Log (optional) is compatible with the AR8000 receiver. The Flight Log displays overall RF link
performance as well as the individual internal and external receiver link data. It also 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
AR8000 receiver. The screen will automatically display voltage i.e. 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 (not used on the
AR8000) L - Antenna fades on the left external antenna R - Antenna fades on the right external
antenna (not used on the AR8000) F - Frame loss H - Holds
Antenna fades—represents the loss of a bit of information on that specific antenna. It's normal to have
as many as 50 to 100 antenna fades during a flight. If any single antenna experiences over 500 fades in
a single flight, the antenna should be repositioned in the aircraft to optimize the RF link.
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. A Hold- occurs when 45 continuous
frame losses occur. This takes about one second. If a hold occurs during a flight, it's important to reevaluate the system, moving the antennas to different locations and/or checking to be sure the transmitter
and receivers are all working correctly.
Note: Use a servo extension to allow the Flight Log to be plugged in without having to remove the
aircraft's hatch or canopy. On some models, the Flight Log can be plugged in, attached and left on the
model using double-sided tape. It is common with helicopters to mount the Flight Log to the side
frame.
