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

- Lower throttle to the lowest position and make sure the transmitter is powered off.
- Insert the bind plug into the BIND/DATA port.
- Insert the receiver battery into ANY open port. The receiver's LED will flash when the receiver is ready to bind.
-
While pressing the Bind button, power on the transmitter.
-
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.
- Remove the bind plug from the receiver.

-
Connect the battery to ESC and turn on the ESC switch, if available. The receiver's LED will flash rapidly when the receiver is ready to bind.
-
While pressing the Bind button, power on the transmitter.
- Release the Bind button after the receiver's LED stays illuminated. This indicates the receiver is bound to the transmitter. The transmitter screen also provides binding information.
- Remove the bind plug from the receiver.
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.
European Union Receiver Requirements
EU versions of the DX8 are not compatible with DSM2 ^® receivers. Make sure all receivers are DSMX ^® compatible.
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 gain.
PROGRAMMING FAILSAFE POSITIONS
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
- Power the transmitter and receiver on.
- 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 be 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:
- Power on the transmitter and receiver.
- Move one of the control sticks to the desired Hold Last Command position and hold the input.
- 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 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:
- Insert the bind plug in the bind port on the receiver and power on the receiver.
-
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.
-
Move the transmitter control sticks and switches to the desired Preset failsafe position. Power the transmitter on.
- Failsafe programming is complete when the orange LEDs on the transmitter and all receivers turn solid.

Auto-Cycle can be selected to Inhibit or Active. If inhibited, the system will go through the list 1 time only. If the switch is triggered again when at the final item in the list, it will not begin at the top of the list. If Active, the system will restart at the beginning of the list after the last item on the list with the next switch trigger.
Steps are used to select the number of items on the list for the system to call. This can be set from 0 to 16 so there can be up to 16 items called to the pilot triggered by the switch selected. Next, select the alert to be spoken for each stepped event on the list as desired. A variety of alerts can be chosen from the list, including telemetry alerts and a variety of flight conditions and commands.

Swashplate
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:
- 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.
- 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).

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.
Gyro
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.

SAIL Mixing
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.
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.

Creating a mix to RAL (Right Aileron) or LAL (Left Aileron) will create different enables you to use fewer mixes to achieve the desired response.
Example 1: Creating a mix AIL > RAL will move the ailerons in opposite directions, while creating a mix AIL > LAL will move the ailerons in the same direction.
Example 2: Create a mix ELE > REL will move the elevator halves together, while mixing ELE > LEL will move the elevator halves in the opposite direction (tailerons).
IMPORTANT: Be sure the right aileron is connected into the AIL port on the receiver and the left Aileron is connected into the Aux1 port on the receiver.
