Spektrum’s DX8 with Integrated Telemetry

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

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.

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.

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.

EN

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.

Rotate the roller to highlight battery type.

Press the roller to access NiMH or LiPo. The low voltage cutoff will default to the recommended voltage for the battery type selected. The voltage cutoff can be adjusted from this screen, but normally the default cutoff of 6.4 volts for LiPo is recommended.

Receiver Installation

In gas and glow aircraft install the main receiver by wrapping it in protective foam and fastening it in place using rubber bands or hook and loop strap.

In electric airplanes or helicopters, you can use thick double-sided foam tape to fasten the main receiver in place.

Mount the remote in a slightly different location from the primary receiver. This gives tremendous improvements in path diversity. Essentially, each receiver sees a different RF environment and this is key to maintaining a solid RF link. This is especially the case in aircraft with substantial conductive materials (e.g., larger gas engines, carbon fiber, pipes etc), which can weaken the signal.

Using servo tape, mount the remote receiver keeping it at least 2 inches away from the primary antenna. Ideally, you should position the antennas

perpendicular to each other. In airplanes, we recommend mounting the primary receiver in the center of the fuselage on the servo tray and the remote receiver to the side of the fuselage or in the turtle deck.

Y-Harnesses and Servo Extensions

Do not use amplified Y-harnesses and servo extensions with Spektrum equipment. Only use standard non-amplified Y-harnesses and servo extensions. When converting existing models to Spektrum, replace all amplified Y-harnesses and/or servo extensions with conventional non-amplified versions

Power System Requirements

Onboard power systems must provide adequate power, without interruption, to the receiver even when the system is fully loaded (servos at maximum flight

loads). Inadequate power systems are a primary cause of in-flight failures. Some components that affect the ability to properly deliver adequate power include: the selected receiver battery pack (number of cells, capacity, cell type, state of charge), switch harness, battery leads and, if used, the regulator and power bus. The AR8000’s minimum operational voltage is 3.5-volts. Test the system per the following guidelines to a minimum voltage of 4.8-volts during ground testing. This will compensate for battery discharging or actual flight loads that are greater than ground test loads.

Recommended Power System Guidelines

1.When setting up large or complex aircraft with multiple high-torque servos, use a current and voltmeter (HAN172). Plug the voltmeter in an open channel port in the receiver, and with the system on, load the control surfaces on your aircraft by applying pressure with your hand. Monitor the current as you load control surfaces. The voltage should remain above 4.8 volts even when all servos are heavily loaded.

2.With the current meter inline with the receiver battery lead, load control surfaces while monitoring the current. The maximum continuous recommended current for a single heavy-duty servo/battery lead is 3 amps. Short-duration current spikes of up to 5 amps are acceptable. If your system draws more than these currents, you need to use multiple packs of the same capacity with multiple switches and multiple leads plugged into the receiver.

3.If using a regulator, perform tests for a 5-minute period. A regulator may provide adequate short-term power, but this tests its ability to maintain voltage at significant power levels over time.

4.For really large aircraft or complex models, multiple battery packs with multiple switch harnesses are necessary. No matter what power systems you choose, always carry out test #1. Make sure the receiver is constantly provided with 4.8 volts or more under all conditions.

CAUTION: When charging any brand of NiMH battery pack, make sure the battery is fully charged. Due to the nature of peak charges and variations in charging rates, heat development, and cell types–the capacity reading of a battery charged on a fast peak charger may only reach 80% of its nominal value. Use a charger that displays total charge capacity. Note the number of mAh put into a discharged pack to verify the charge is at full capacity.

Binding

You must bind the receiver to the transmitter before the receiver will operate. Binding teaches the receiver the specific code of the transmitter, so it will only connect to that transmitter.

1.To bind an AR8000 to a DSM2 transmitter, insert the bind plug in the BATT/ BIND port on the receiver.

SPEKTRUM DX8 • RADIO INSTRUCTION MANUAL

11

EN

Note: To bind an aircraft with an electronic speed controller that powers the receiver through the throttle channel (ESC/BEC), insert the bind plug into the BATT/BIND port in the receiver and the throttle lead into the throttle (THRO) port. Proceed to Step #2.

2.Power the receiver. The LED on the receiver will be flashing, indicating the receiver is ready to be bound to the transmitter.

3. Move the sticks and switches on the transmitter to the desired failsafe positions (low throttle and neutral control positions).

4.Press and hold the trainer button while powering on transmitter.

5.The system will connect within a few seconds. Once connected, the LED on the receiver will go solid indicating connection.

6.Remove the bind plug from the BATT/BND port on the receiver. Power off the transmitter and store the bind plug in a convenient place.

NOTICE: Remove the bind plug to prevent the system from entering bind mode the next time the power is turned on.

7.After setting up your model, rebind the system so the true low throttle and neutral control surface positions are set.

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 Command Failsafe, and Preset Failsafe.

SmartSafe Failsafe

SmartSafe Failsafe is always active in both hold last command failsafe and in preset failsafe. SmartSafe is a safety feature on the throttle channel only that offers the following benefits:

•Prevents electric motors from operating when the receiver only is turned on

(no signal present)

•Prevents the speed controller from arming until the throttle is moved to low throttle position after connection is made

•Shuts off electric motor and reduces gas/glow engines to idle if signal is lost

•If throttle is at any position other than low, the ESC won’t arm

•If connection is lost in flight:

-SmartSafe sets the throttle to the position it was in during the binding process.

How To Program

SmartSafe is automatically set when hold last command failsafe or Preset failsafe is programmed or the system is bound. Note: It’s important to have the throttle stick in the low position to store low throttle during binding

To Test

Confirm the failsafe setting is correct by turning off the transmitter. The throttle should go to the preset low throttle position.

CAUTION: Make sure the aircraft is restrained on the ground. If failsafe is not set, your aircraft might advance to mid or full throttle.

Hold Last Command

If you lose connection, all channels except for throttle channel hold last given command and the aircraft continues on its path. So, if you were turning when connection was lost, your aircraft would continue turning.

How to Program

1.Leave the bind plug in the bind port through the entire binding process.

2.Remove bind plug only after receiver connects to transmitter

To Test

Confirm the failsafe settings are correct by turning off the transmitter. All channels except for the throttle should hold the last command.

CAUTION: Make sure the aircraft is restrained on the ground. If failsafe is not set, your aircraft might advance to mid or full throttle.

Preset Failsafe

If the signal is lost, all channels are driven to their failsafe position set during binding.

Preset Failsafe is ideal for sailplanes, as spoliers can be deployed during loss of signal, preventing a flyaway.

How To Program

1.Insert the bind plug and power on the receiver.

2.When the receiver LEDs blink indicating bind mode, remove bind plug before binding the transmitter to the receiver.

3.LED lights will continue to blink.

4.Move transmitter’s control sticks and switches to the desired Preset Failsafe positions then turn it on in bind mode.

5.The system should connect in less than 15 seconds.

NOTICE: Failsafe features vary according to receiver, so if using a receiver other than the AR8000, consult your receiver’s instructions for the failsafes that apply.

Before flight, ALWAYS confirm your binding is good and failsafe is set. To do this, make sure the system is connected, turn your transmitter off. Confirm that low-throttle is active.

CAUTION: Make sure the aircraft is restrained on the ground. If failsafe is not set, your aircraft might advance to mid or full throttle.

Model Select

The Model Select function is used to change to a different model memory, typically when switching from the current model. You can store up to 30 models in the DX8’s model memory. You can access the model select function through the System Setup mode or through Direct Model Access. Direct Model Access allows you to access the model select function at any time the main screen or a telemetry screen is displayed.

Direct Access Model Select

Press the Clear and Back buttons simultaneously to access the Model Select screen

To directly access the Model Select Screen any time from the Main Screen or the Telemetry screen, press the Clear and Back buttons simultaneously. The Model Select screen displays for 10 seconds. If no activity occurs, the screen returns to the previous Main or Telemetry screen.

To Access the Model Select Function through System Mode

Press and hold the roller while turning on the transmitter. When System Setup appears on the screen, release the roller. The DX8 is now in System Setup Mode. Highlight Model Select then press the roller to access the function.

The following screen appears. Rotate the roller to highlight the desired model then press to select. The model name will display on the main screen.

ModelMatch

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.

Model Type

Model Type programs the selected model memory to function in Helicopter or Airplane programming. You should program Model Type first when setting up a new model. Note: You can assign each model memory its own model type.

To Access the Model Type Function

Press and hold the roller while turning on the transmitter. When System Setup appears on the screen, release the roller. The DX8 is now in System Setup Mode.

Rotate the roller to highlight Model Type then press to access the function. The following screen appears:

Rotate the roller to highlight the desired model type (Helicopter or Airplane) then press the roller to select.

You can return to the System Setting screen at anytime by pressing the Back button on the transmitter once.

Model Copy

The Model Copy function copies the currently selected model’s programming of another model memory. Thirty model memories are available. Some of the more common uses of the Model Copy function include:

•Moving the order of models around in model memory so they can be organized by category, type, etc. Note: You will need to re-bind after moving models.

•Experimenting with the programming for an aircraft while preserving a copy of the original setup. Note: If you want to use the model copy function to try two slightly different setups with the same model you will need to rebind the receiver each time you switch between model memories.

•Copying the programming for an existing model over to a new model that is similar. Many pilots find this to be a good way to provide more accurate baseline programming for the new model. For example Vibe 50 w/120CCPM mixing, gyro and governor programming provides a good base programming for any other nitro powered 120CCPM mixing helicopter. An Extra 300 with

dual aileron and elevator servos that is properly programmed with dual flap and dual elevator mixing in Wing Type provides good foundational programming for another aerobatic airplane with the same basic control system.

Important: The model memory you are copying to will be over-written by the copied programming, permanently deleting any programming that may already exist.

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.

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.

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 over-discharging 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.

EN

RPM (optional sensor sold separately)

Two RPM sensors are available: SPMA9569 for nitro and gas engines, SPMA9558 for brushless electric motors.

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 magnetic metal by locating the sensor within 5 mm of the rotating steel object.

Note: On some engines you may need to space the sensor further away from the backplate. The sensor picks up the crankpin only; on some engines if the sensor is too close, it will not distinguish the crankpin from the crank weight.

Installation

Install the backplate sensor in the backplate.

Install the connector into the RPM port in the TM1000.

Testing

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.

SPEKTRUM DX8 • RADIO INSTRUCTION MANUAL

19

EN

Electric RPM Sensor

The optional electric RPM sensor is designed to be used with any brushless motor. The sensor has two leads to attach to any two of the three motor wires. This is typically done by soldering.

Installation

To install the electric RPM sensor using servo tape, attach the sensor in a convenient place that allows the leads to reach the motor wires and the TM1000 telemetry unit.

Solder the two sensor wires to any two motor leads.

Plug the sensor lead into the RPM port on the TM1000 telemetry module.

Testing

Turn the transmitter and receiver on and scroll to the RPM telemetry screen. Run the motor and the RPM should register on the screen.

The RED LED on the TM1000 indicates the sensor is picking up properly.

NOTICE: It is necessary to program a matching pole count in the telemetry RPM screen to have accurate reading on screen. The motor’s pole count is normally in the motor manufacturer’s instructions or on the manufacturer’s website.

Frame Rate

The Frame Rate function allows the selection of 11ms or 22ms frame rate. When a 11ms frame rate receiver is used, the transmitter defaults to 11ms frame rate. This fast frame rate is not compatable with some types of analog servos and the Frame Rate screen allows the selection of a 22ms frame rate when a high frame rate receiver is being used with analog servos.

To access the Frame rate Function

Press and hold the roller while turning on the the transmitter. When system setup appears on screen relese the roller. The DX8 is now in System Setup mode.

Rotate the roller to highlight Frame Rate then press. The following screen appears:

Rotate the roller to highlight the frame rate then press. Now rotate the roller to select 11ms or 22 ms frame rate.

Trainer

The DX8 features a programmable trainer function with three trainer modes. The transmitter assigns the trainer function to the trainer button. The function activates when the switch is depressed and one of the three trainer modes is selected. The three trainer Modes include:

Inhibit

In Inhibit you can use the transmitter as a slave only. However, the slave transmitter must have the same programming as the master (e.g., servo reversing, travel adjust, sub-trim, trims).

Programmable Master

With Programmable Master you can program the transmitter to transfer any or all channels when you activate the trainer switch. This is ideal for beginners so the student learns control of 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 the slave transmitter (i.e. Servo reversing, wing type, Sub trim, Travel Adjust, Mixing, etc.) must match the master’s transmitter programming. If two DX8’s are being used simply copy and transfer the model memory using the SD card from the master’s model to the slave. The slave transmitter is then programmed to inhibit in the trainer screen.

Pilot Link Master

When Pilot Link Master is selected the slave transmitter has control of the stick function only (aileron, elevator rudder and throttle) while the master maintains control of all other channels and functions including D/R and switch positions. This is ideal for complex models as the master maintains control of all secondary functions and controls all other channels.

Slave

Use Slave mode when flying with the DX8 as a slave when the master radio has activated its Pilot Link. In this case, there is no need to match programming between the slave and master transmitter.

System Settings

Use the System Setting screen to establish the overall transmitter setting that will apply to ALL model memories. These settings include: User Name, Contrast, Mode, Region and Language. If you select Mode One, then Mode One will be selected for all 30 model memories. Note: Even when models are imported from an SD card the system settings in the transmitter will remain.

Differential

The Differential function provides precise adjustments of up/down aileron travel of each aileron (or elevon if Delta wing is activated). Typically, you can use Aileron differential to reduce unwanted yaw characteristics. In aerobatic airplanes adjusting differential provides an axial roll (minimum displacement of yaw during a roll). You can program up to three Differential values and assign them to a switch. Note that positive + and negative – differential is available; however, normally more up aileron travel is required than down aileron.

Note: The Differential function is only available if Dual Aileron, Flaperon, 2 ailerons 1 flap, 2 ailerons 2 flaps or Elevon is selected in Wing Type (see page 13) and each aileron servo is controlled by its own channel.

Swashplate

The Swashplate screen adjusts the amount and direction of travel for the aileron, elevator and pitch functions when you activate CCPM mixing in Swash Type (see pages 15-16). This screen also allows an Expo function that compensates for the effect of the servo’s rotation at extremes of travel. An E-ring function also prevents servo over-travel when simultaneous extreme aileron and elevator inputs are given. Unless using a linear servo or a type of linkage that eliminates this effect, you should turn on the Expo function when any CCPM mix is enabled. Swashplate values increase or decrease the overall control travel of the selected channel. For example if you increase Pitch value, the travel of all three servos that control pitch will increase. If you increase aileron, the aileron and pitch servos will increase. Increasing or decreasing this value affects the travel of that function and not the individual servo. Note: Negative and positive swashplate values are available.

To achieve the correct travel direction for Aileron, Elevator and Pitch, first use the reversing function to set the servo direction on the aileron, elevator and pitch

channels. Do this so that when an aileron input on the transmitter’s stick tilts the swashplate right and left, an elevator input tilts the swashplate fore and aft, and a pitch input raises and lowers the swashplate. You synchronize the outputs with this function. Then you can adjust swashplate values positively or negatively to achieve the overall correct travel direction for aileron, elevator and pitch.
