EN BINDING Binding is the process of programming the receiver to recognize the GUID (Globally Unique Identifier) code of a single specific transmitter. You must bind the AR8000 receiver to your transmitter before it will operate. The AR8000 requires the remote receiver to be connected to bind. Binding Using the Receiver and Receiver Battery Binding Using the Receiver and ESC D F C D F C D F C D F C D F C D F C D F C D F C 1. Lower throttle to the lowest position and make sure the transmitter is powered off. 2. Insert the bind plug into the BIND/DATA port. 3. Insert the receiver battery into ANY open port. The receiver’s LED will flash when the receiver is ready to bind. 4. While pressing the Bind button, power on the transmitter. 5. Release the Bind button after the receiver has stopped flashing rapidly, once the receiver’s LED stays illuminated; this indicates the receiver is bound to the transmitter. The transmitter screen also provides binding information. 6. Remove the bind plug from the receiver. 1. Lower the throttle to the lowest position and make sure the transmitter is powered off. 2.

EN 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 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�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 DX8 are not compatible with DSM2® receivers. Make sure all receivers are DSMX® compatible. European Union Receiver Requirements

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 instruction 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 sailplanes 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.

EN The Swashplate menu option enables you to adjust the following: •� Swashplate�Mix •� Exponential •� E-Ring •� Elevator Compensation Use�positive�or�negative�Swashplate�mix�values�as�needed�for� correct direction response of the helicopter. Before�making�adjustments�to�the�Swashplate�mix,�make�sure�the� throttle/collective pitch input moves the entire swashplate up or down. If the servos are not moving in the same direction, reverse them as necessary in the Servo Setup menu option. When the entire swashplate moves up or down: 1.�Adjust�the�mix�value�for�the�Aileron�and�Elevator�channels.�If� the servos do not move in the correct direction, change the direction�of�the�mix—for�example,�a�positive�value�instead�of� a negative value. 2.�Adjust�the�mix�value�for�the�Pitch.�If�the�swashplate�does�not� move in the correct direction, change the direction of the value (negative instead of positive). Always�enable�Expo�when�using�a�standard�rotating-arm�servo. The�Expo�delivers�linear�movement�of�the�swashplate�from�a� standard�rotary�servo.�When�Expo�is�inhibited,�the�arm�on�a� rotary servo moves on a curved path with decreased swashplate movement�at�the�extremes�of�the�servo�arm�travel.� NOTICE: Do�not�enable�Expo�when�using�a�linear�servo. Electronic E-Ring This feature prevents over driving servos by limiting servo travel if the�sum�of�your�cyclic�and�pitch�inputs�exceeds�servo�limits. The Gyro menu option enables you to assign a gyro gain value to an independent switch or a Flight Mode. Assign the receiver channel connected to the gyro, then assign the switch for gyro options. You can also assign values to available switch positions (from 1 to 4 rates are available, depending on the switch assigned). Make sure the gyro operates correctly and compensates in the correct direction. Cyclic to Throttle Cyclic�to�Throttle�mix�prevents�rpm�loss�when�aileron,�elevator�or� rudder�inputs�are�given.�This�mix�advances�the�throttle�position� with cyclic or rudder control to maintain rpm. At full throttle, Cyclic to�Throttle�mixing�prevents�the�throttle�from�over�driving�the�servo. IMPORTANT: Do�not�use�Cyclic�to�Throttle�mix�when�using�a� governor. To�verify�that�the�Cyclic�to�Throttle�mix�is�working�properly�and�in� the correct direction, move the flight mode switch to one of the active positions. Move the programmed cyclic or rudder channel, noting the throttle position. The throttle position should increase. If the throttle decreases, then the opposite value (positive vs. negative) is needed. Swashplate The�Swashplate�Mix�typically�corrects�swashplate�timing�issues�by� mixing�Aileron�to�Elevator�and�Elevator�to�Aileron.�When�adjusted� correctly, the Swashplate causes the helicopter to roll and pitch accurately with minimal interaction. The�Tail�Curve�function�mixes�tail�rotor�input�with�the�throttle/ collective function to counter torque from the main rotor blades when using a non-heading hold (tail lock) gyro or when using rate mode on a gyro.

EN Use the Sailplane Type Screen to select wing and tail types to match your sailplane model. Diagrams and setup names show on the transmitter screen to show the available setups. Refer to spektrumrc.com for more information about new DX8 AirWare updates to support these options. * Selection of multiple ailerons activates the Differential menu option. ** “V-Tail A” and “V-Tail B” function as internal servo reversing. If V-Tail A does not work correctly with your aircraft, try V-Tail B. Camber Preset is only available when 2 aileron wing type is selected in Sailplane Type. The Camber Preset function enables you to program the ailerons, flaps, wing tips and elevator for a specific position in each Flight Mode. If flight modes are not active, only one preset position is available and it is always active. The Camber Preset Speed enables the control surfaces to transition over a period of time, up to 30 seconds, when you change flight modes. Move the flight mode switch to the desired position to change the Camber Preset values. Sailplane Model Type NOTICE: Refer to your sailplane manual for recommended control throws. CAUTION: Always do a Control Test of your model with the transmitter after programming to make sure your model responds as desired. Camber System is only available when 2 aileron wing type is selected in Sailplane Type. The Camber System allows in-flight camber adjustment and is also used as the braking system, often referred to as Crow or Butterfly. The Camber System enables you to assign the Camber System to a different switch in each flight mode.

EN SAIL (SAILPLANE) Aileron to Rudder The�Aileron�to�Rudder�mix�is�commonly�used�for�coordinated�turns.� When active, as aileron is applied the rudder moves in the same direction as the turn (right aileron input results in right rudder output). If you assign the flight mode to a switch, a Sub Switch option allows you to assign an additional switch to activate up to 3 Aileron�to�Rudder�mixes�for�that�flight�mode. Aileron to Flap The�Aileron�to�Flap�mix�allows�the�entire�trailing�edge�of�the�wing� (aileron and flap) to operate as ailerons. When active, as aileron is applied the flaps also move. Always program the flaps to move in the same direction as the turn (so that right aileron is equivalent to flaps moving as right ailerons). Elevator to Flap Elevator�to�Flap�mix�creates�additional�lift,�allowing�a�tighter�turn.� The entire trailing edge of the wing (aileron and flap) operates as flaps (camber increase) when you apply elevator. An offset is provided, which is typically used for Snap Flaps. With Snap Flap, no�Elevator�to�Flap�mix�occurs�until�the�offset�value�is�reached.� Typically, this offset is at 70% up elevator so that beyond 70% the�down�flap�mix�comes�in,�providing�additional�lift�for�more� aggressive turning (for tight thermals or racing turns). Flap to Elevator Flap�to�Elevator�mix�prevents�pitch�up�tendency�that�occurs�when� you�apply�Crow�or�Butterfly.�This�mix�is�typically�used�only�with�the� Camber�System.�The�Flap�to�Elevator�mix�operates�as�a�curve�so� that the elevator moves down the most during the first 20% of flap deployment,�decreases�over�the�next�40%,�then�remains�the�same� from 60 to 100% of flap travel. For sailplanes with ailerons/tips/flaps, make sure an appropriate Sailplane Type is selected so that tips appear in the transmitter as RAIL and LAIL. Decrease or increase travel on the tip ailerons by creating�an�AIL�>�RAIL�mix.� For�each�of�these�mixes,�you�can�program�each�flight�mode�with�different�mix�values�or�at�0%�if�no�mix�is�desired�for�that�specific�flight� mode. Programming values include independent control of the direction and amount a slave surface moves in relationship to the master surface. The V-Tail Differential screen enables you to increase or decrease the amount of differential between control surface throws. Positive Differential values decrease the amount of “down” travel without affecting the “up” travel on the opposite control surface. Negative Differential values decrease the amount of “up” travel without affecting the amount of “down” travel on the opposite control surface. The V-Tail Differential menu option only appears when V-Tail A or V-Tail B is active in Aircraft Type. To adjust the V-Tail Differential: 1. Scroll to Switch and press the scroll wheel. Scroll right to select�On�(Differential�is�always�on)�or�assign�the�differential�to� a switch position. 2. Press the scroll wheel a second time to save the selection. 3.
