BINDING

Binding is the process of programming the receiver to recognize the GUID (Globally Unique Identifier) code of a single specific transmitter. The DX18 and AR9020 are pre-bound at the factory. You will need to rebind after the model programming is initially set up to fully program the model's failsafe positions.

2. Insert the bind plug into the BIND/DATA port.
3. Insert the ESC plug into the THRO port.

4. Connect battery to ESC and turn on ESC switch, if available. The receiver's LED will rapidly flash when the receiver is ready to bind.

5. While pressing the Bind button, power on the transmitter.

6. 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 screen also provides binding information.
7. Remove the bind plug from the receiver.

CAUTION: When using the DX18 with parkflyer receivers, only use such receivers in parkflyer-type aircraft (small electric airplanes or mini and micro helicopters). Installing parkflyer receivers in larger aircraft could cause signal blocking and

loss of connection.

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

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 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 heading 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 little 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 fl yaway 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 fl ash rapidly. The orange receiver LEDs will continue fl ashing.

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 might advance to mid or full throttle.

X-PLUS™

The X-Plus™ 8 module is designed to allow expansion of up to 8 servos for non-control surface functions such as bomb drops, lights, winches, retractable landing gear, and many more. The X-Plus 8 is compatible with Spektrum™ X-Plus transmitters and receivers. The X-Plus 8 module offers the option to power the connected servos via dual auxiliary battery ports with separate batteries and switch harnesses (sold separately) independent of the receiver. The X-Plus 8 module can also be powered inclusive of the receiver by using the included jumper through either of the dual BATT/JMPR ports.

Features:

• 8-channel expansion
• Dual battery ports
• Included Jumper offers option of using receiver power
• Allows fi ne tuning of 8 servos on non-critical controls (bomb drops, lights, winches, gear, etc.)

Applications

Scale modelers with complex aircraft, ships, or surface applications will enjoy the easy programming and functions of the X-Plus 8 module using X-Plus compatible transmitter's AirWare™

software. Modelers will be able to select 2 position,

3 position or potentiometer adjustment through their transmitter.

After selecting the specific switch or port, AirWare software will allow the individual servo adjustment of each X-Plus channel's travel adjust, sub trim, reversing, and speed.

Specifications

Type: X-Plus Module

Channels: 8

Dimensions: 0.91x 1.61 x 0.79 in

$$ (2 3 \times 4 1 \times 2 0 \mathrm{mm}) $$

Weight: .42 oz (11.9 g)

Voltage Range: 3.5 to 9.6V

Resolution: 512

Compatibility: All X-Plus transmitters and receivers

Installation

In gas and glow aircraft, install the X-Plus 8 module by wrapping it in protective foam and fastening it in place using rubber bands or a hook and loop strap. In electric airplanes or helicopters, you can use thick double-sided foam tape to fasten the module in place.

When using an X-Plus receiver and module, it is recommended that the X-Plus 8 module be mounted as near to the receiver as possible. When using the jumper lead to power the module, mounting the X-Plus 8 module near the receiver system will minimize the current loss from the receiver. Servo extensions can be used with each servo, but we recommend using heavy 22 gauge wire with gold-plated connectors.

A power jumper plug must be installed in one of the BATT/JMPR ports of the module if the module is powered from the receiver through the SRXL port.

Always remove the power jumper when an auxiliary battery or auxiliary batteries are used. When the auxiliary battery option is used, the X-Plus 8 module can be mounted as far away from the receiver as needed to be near connected servos.

Power System Requirements

Inadequate power systems that do not provide the necessary minimum voltage to the receiver during flight are 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 X-Plus 8 module has a minimum operational voltage of 3.5 volts; it is highly recommended that the power system be tested per the guidelines below.

Recommended Power System Test Guidelines

If a questionable power system is being used (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.

Plug the voltmeter into 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.

X-Plus Channels and Failsafe

Failsafe is not supported for servos connected to the X-Plus Module. We recommend that no failsafe should be expected or attempted for a servo connected through the X-Plus Module. However, servos connected to the X-Plus Module will hold last command in the event of a failsafe condition.

To Activate X-Plus

1. Open the Frame Rate Menu in System Setup.
2. Scroll to X-Plus and press the scroll wheel to activate. The X-Plus Inputs screen is now active in the Channel Assign menu.

AUX6 and AUX7 channels are available on 12-channel receivers when X-Plus is active. AUX6 and AUX7 are 2048 resolution and 22ms frame rate (12-channel receivers only).

Channels X+1 and X+2 are duplicate channels of channels 11 and 12 on a 12 channel receiver with X-Plus active. If channels 11 and 12 require any adjustment for travel adjust, servo reversing, sub trim or any other function, adjust channels X+1 and X+2. Note that channels 11 and 12 will also show on the X-Plus monitor as channels X+1 and X+2.

If you select 11ms frame rate before you activate X-Plus, the transmitter reverts to 22ms frame rate when X-Plus is active.

CAUTION: Do NOT connect throttle or any primary control surface to the X-Plus Module. The X-Plus change intended to be used for auxiliary functions only. X-Plus cells have a resolution of 512 and variable latency from 0 to about 88ms. When X-Plus is active, the first 10 channel fault to 22ms.

Trainer

The DX18 features a programmable trainer function with 4 wired trainer modes and 2 wireless trainer modes. The transmitter assigns the trainer function to Switch I.

Wired Trainer

The 4 wired trainer modes include:

Inhibit

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

Programmable Master

Programmable mode enables you to program the master transmitter to transfer any or all individual channels when you activate the trainer switch. This mode is ideal for beginners

learning to control individual channels while the master transmitter maintains control of all other channels.

The slave transmitter should be in Inhibit mode, if available. The Master and Slave transmitters MUST have the same programming.

Pilot Link Master

Pilot Link Master enables you to program the master transmitter to transfer any or all individual channels when you activate the trainer switch. Pilot Link Master is ideal for complex models, as the master transmitter can maintain control of all secondary functions—for example flight modes, retracts, flights and brakes. Secondary functions can be individually assigned to the Slave transmitter as necessary. It is not necessary to have model programming in the slave transmitter.

It may be necessary for the slave transmitter to be in Inhibit mode to allow trim changes to transfer over from the master transmitter.

Slave

Use Slave mode when using the DX18 as a slave transmitter and Pilot Link is active in the master transmitter.

Wired Trainer Operation

1. Bind the master transmitter to the model.
2. Connect the trainer cord (SPM6805) to the back of the master transmitter.
3. Make sure the master and slave transmitter battery packs are fully charged.
4. Make sure the slave transmitter is powered off. The slave transmitter receives power when you connect the trainer cord.
5. Connect the trainer cord to the slave transmitter.
6. The slave transmitter screen displays information but does not send a signal to the model.
7. Press the trainer button on the master transmitter to transfer model control from the master to the slave.
8. While moving the trainer switch between the off and on positions, watch for movement on the control surfaces. Adjust the trims as necessary before fl ying.
9. Release the trainer button and the master transmitter regains control of the model.

Master Override

The Master Override feature enables the instructor to immediately regain control of the model by moving the control sticks. After you activate Master Override, the slave transmitter cannot control the model until you reset the trainer switch. To reset the trainer switch:

1. Move the trainer switch to the OFF position.
2. Move the trainer switch to the ON position to activate the slave transmitter.

Wireless Trainer

Wireless Trainer works just like the Wired Trainer, without the wire. Select Wireless Trainer to bind a DSM2 or DSMX slave transmitter to the master transmitter. With this option, when the master presses the trainer button or switch, control is given to the currently bound slave transmitter. After binding, the slave transmitter will remain bound to the master transmitter until a different transmitter is bound to the master, or the slave transmitter is bound to another receiver or a wireless master transmitter. ModelMatch™ technology applies to the wireless trainer system; the master transmitter will be bound to the slave in the bound model used. Also if the slave transmitter has ModelMatch technology, it will only be bound to the master transmitter in the selected model during binding.

Inhibit

In Inhibit, the wireless trainer function will be inhibited and will not function.

CAUTION: Select Inhibit in the Trainer menu when you are not using the wireless trainer function. Failure to select Inhibit result in loss of control of the aircraft.

Programmable Master

Programmable mode enables you to program the master transmitter to transfer any or all individual channels when you activate the trainer switch. This mode is ideal for beginners

learning to control individual channels while the master transmitter maintains control of all other channels. The slave transmitter should be in Inhibit mode, if available. The Master and Slave transmitters MUST have the same programming.

Pilot Link Master

Pilot Link Master enables you to program the master transmitter to transfer any or all individual channels when you activate the trainer switch. Pilot Link Master

is ideal for complex models, as the master transmitter maintains control of all secondary functions, such as flight modes, retracts, fl aps and brakes.

Secondary functions can be individually assigned to the Slave transmitter as necessary. It is not necessary to have model programming in the slave transmitter.

Wireless Trainer Operation

1. Enter an unused model on the slave transmitter (computer transmitter only).
2. Bind the master transmitter to the model.
3. Make sure the master and slave transmitter battery packs are fully charged.

4. Make sure the slave transmitter is powered off.

Throttle Cut

The Throttle Cut menu option enables you to assign a switch position to stop an engine or motor. Throttle Cut activates regardless of flight mode.

When you activate Throttle Cut, the throttle channel moves to the pre-programmed position (normally off).

You may need to use a negative value to move the throttle channel to the off position.

CAUTION: Always test the model after making adjustments to make sure the model responds to s as desired.

Throttle Curve

You can use the Throttle Curve menu option to optimize the throttle response. A maximum of 7 points are available on the throttle curve.

To add points to a Throttle Curve:

1. Move the throttle stick to the position where you wish to add the new point.
2. Scroll to Add Pt. and press the scroll wheel to add the point.

To remove points from a Throttle Curve:

1. Move the Throttle stick until the cursor is near the point you wish to remove.
2. Scroll to Remove Pt. and press the scroll wheel once to remove the point.

Mixing

Mixing allows control input for a channel to affect more than one channel at a time. Mixing functions support:

• Mixing a channel to another channel.
• Mixing a channel to itself.
• Assigning offset to a channel.
• Linking primary to secondary trim.

These mixes are available for each model memory:

• 16 programmable mixes
• Cyclic to Throttle (HELI)
- Swashplate (HELI)
• Elevator to Flap (ACRO)
- Aileron to Rudder (ACRO)

• Rudder to Aileron/Elevator (ACRO).
• Aileron>Rudder (SAIL)
• Aileron>Flap (SAIL)
• Elevator>Flap (SAIL)
• Flap>Elevator (SAIL)

Select a channel for master and slave. Inputs for the master channel control both the master and slave channels. For example, Elevator to Flap makes elevator the master channel and flap the slave channel.

Offset

Change the offset value to move the effective center position of the slave channel. Positive or negative value determines the direction of the offset. Offset is not available for curve mixes.

If you program multiple throttle curves and you wish to edit one of the curves, that curve must be active in the Throttle Curve screen before you can make any changes.

Trim

If the master channel trim should also adjust the slave channel, set Trim to Act. A channel monitor on the left side of the screen shows how channels respond to input. To view a switch-

assigned mix on the monitor, the mix switch must be in the active position.

Assigning a Mix to a Switch

If you wish to assign a mix to a switch position:

1. Scroll to Switch and press the scroll wheel.
2. Scroll left or right to the switch you wish

to use and press the scroll wheel to save the selection.

1. Scroll to the switch position where you want the mix to be active.

The mix is Active when the box is filled and inactive when the box is open. You can assign a mix to be active in multiple switch positions (0,1 or 2).

CAUTION: Always do a Control Test of your model after changing mixes.

Combo Mixing

Combination Mixing is available to create OR mixing. OR mixing allows you to assign 2 conditions where the mix will activate if either condition occurs. You can also create AND mixing where 2 conditions must occur to activate the mix.

To program Combination Mixing:

1. Activate a mix.
2. Select Combo Sw. in the Switch Selection. The Combo screen appears.
3. Select the desired switch and active switch position for Switch 1. The mix is Active when the switch position box is filled.
4. Select the Relation (AND, OR)
5. Select the desired switch and active switch position for Switch 2. The mix is Active when the switch position box is filled.
6. Press the BACK button to save the Combination Mix.

The Master (left side) names are inputs. For example, “Aileron” refers to the Aileron Stick. The Slave (right side) name is the name of the channel receiving the mix command when the Master channel moves.

Back Mixing

Back Mixing applies a mix to all related servos in a wing or tail type. For example, if you select 2 AIL, 2 FLAP in the Aircraft Type screen, a mix to one aileron channel affects both aileron servo

The mix response, however, depends on the aileron channel included in the mix.

A Back Mix also enables you to use fewer mixes to achieve the desired response, for example adding roll to a split elevator.

1/2 Mixing Values

When adjusting the mix values near center (below 10), 1/2% mix values are available for fi ne adjustment capability.

IMPORTANT: This function is only available in program mixes and rudder to aileron/elevator in aircraft model type.

Origin Mixing

Origin Mixing uses true stick position as the input for a mix. When origin mixing is selected, any other settings to the master channel will be ignored and the mix will

be based strictly on stick position and trim position. When Aileron, Elevator, or Rudder are selected as the master, origin mixing is available. Once Aileron, Elevator, or Rudder are selected, an N will appear next to the master channel, where N means normal. Roll and select the N to change to O for origin mixing. Next, select the slave channel and set the switch and mix rates as desired.

Sequencer

The Sequencer menu option provides this-then-that mixing with a time delay. Five different sequences (S1 through S5) are available to control 2 functions each (A and B), in 2 timing directions (forward or reverse). Sequences appear throughout function screens as assignable switches.

CAUTION: Always review the action of a sequence on the Monitor or X-Plus Monitor screen BEFORE operating the to ensure controls act as desired. Failure to do so could a crash, resulting in property damage and or injury.

You can program multiple functions to sequentially activate in response to an assigned switch. For example, an assigned Gear switch can open gear doors, lower the gear, then close the doors. In reverse, gear doors open, the gear retracts and the gear doors close.

You can assign each Sequencer function to a switch in most Function screens such as Flight Mode, Dual Rate, Mixing, Throttle Curve, Pitch Curve, etc.

You can assign several functions to a sequence to decrease the number of controls you need to touch during complex flight transitions—for example, applying your assigned dual rates and exponential when the landing gear deploys and the flight mode changes.

If you select an S-Number-A sequence (e.g. S3A), the sequence operates as a timed 5-position switch. An S-Number-B sequence operates as a timed 3-position switch. The 5 positions correspond to the sequencer values shown on the time delay graph in the second Sequencer screen. In a function screen, highlight each point (0–4) and select the switch position desired for a function to be active.

When S1B (or another sequence-number-B) is selected as a switch in a function, the sequence will operate as a timed 3-position switch. The 3 positions act as 'kick points' of the movement at fixed percentages (equal thirds) of the sequencer output. In a function screen, highlight each point (0–2) and select the switch position desired for a function to be active.

Sequencer Set Up

1. In the first Sequencer screen, select 1 of the 5 available sequences.
2. In the second Sequencer screen, assign a switch to the sequence. We recommend using a 2-position switch.

Tip: If you need to

use a 3-position switch, you must assign one direction to two adjacent switch positions—e.g., 0 and 1. Assign the opposite direction to the third switch position.

1. Assign the timing for the Forward and Reverse directions as desired. There is no delay when you use the Nor option. You may also select a delay time between 0 and 30 seconds.
2. Assign names for each sequencer function as desired.
3. Select either Step (S) or Proportional (P) for the Sequencer output.

Step: The sequence only changes at kick points. Otherwise, there is a delay in the sequence until it reaches the next kick point.

Proportional: The sequence movement is proportional between kick points. The sequence maintains rate and direction until it reaches the next kick point.

1. Adjust the Sequencer motion percentages in the third screen.

For example, you may move points 1, 2 and 3 closer to the beginning of the sequence so the motion occurs earlier.

This results in a delay between point 3 and point 4 at the end of the sequence.

Testing the Sequence

The Sequencer function determines the response for channels included in the sequence.

Refer to the Monitor screen to see how respective channels interact in the Sequencer.

Range Test

The Range Test function reduces the power output. This allows for a range test to confirm the RF link is operating correctly. Perform a range check at the beginning of each flying session to confirm system operation

To Access the Range Test screen

mode the RF output is reduced allowing for an operational range test of your system.

1. If you let go of the trainer button, the transmitter will go back to Full Power.

Range Testing the DX18

1. With the model restrained on the ground, stand 30 paces (approx. 90 feet/28 meters) away from the model.
2. Face the model with the transmitter in your normal flying position and place the transmitter into Range Test mode (see above) and push the trainer button, reducing the power output.
3. Operate the controls. You should have total control of your model with the transmitter in Range Test mode.
4. If control issues occur, contact the appropriate Horizon Product Support offi ce for assistance.
5. If performing a range test while a telemetry module is active, the display will show flight log data.

Timer

The DX18 Timer function allows you to program a countdown timer or stop watch (count up timer) to display on the main screen. An alarm sounds when the programmed time is reached. You can program the timer to start using the assigned switch position or automatically when throttle is raised above a programmed position. An internal timer that shows run time for a specific model displays on the Main Screen. A total system timer is also available.

Timer Event Alerts

The Timer Event Alerts screen enables you to select an action for each type of alert. The available options are:

• Inh (Alert Off)
• Tone
  • Vibe
• Tone/Vibe
  • Voice
• Voice/Vibe

Timer Control Alerts

The Timer Control Alerts screen enables you to select Inh (Off), Tone or Voice for Timer Start, Timer Stop and Timer Reset.

Telemetry

Telemetry is in both the system setup and the function list so you can access the telemetry functions from either list.

You must power off the receiver and transmitter, then power them both on to reset the telemetry data. You can reset min/max values by pressing the CLEAR button.

NEVER change Telemetry settings when the aircraft is powered on. There is a brief interruption in RF output when exiting the Telemetry screen, and may cause a "Hold" condition.

Custom Voice Setup

Use the custom voice setup function to set up custom voice alerts or messages. For example, with the custom voice setup function you can be alerted to a switch change report or a sequence of alerts using the Stepping Events option. To add a new custom voice alert or command, enter the Custom Voice Setup function and select Add New Sound Event with the roller. Select either Switch Change Report or Stepping Events.

Switch Change Report

Use this feature to have telemetry read in a certain switch position, current switch position, or a variety of other alerts such as "Landing Flaps" or "Mix On". Begin by selecting the switch you wish to use for the spoken alert, then select the desired setting next to each switch position.

Stepping Events

Stepping Events can be used to provide voice alerts when a switch is moved stepping through a list of events. Begin by selecting the switch desired to trigger each step through the list (when the switch is triggered as selected, the system will move to the next item on the list going through the list of user-defi ned selections one by one.) 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 fi nal 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 is 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 fl ight conditions and commands.

System Setup

Press here to enter the System List from the Function list without turning the transmitter off. A Caution screen will appear that warns that RF will be disabled (the transmitter will no longer transmit). Press YES if you are sure and want to access the System List. If you are not sure, press NO to exit to the main screen and continue operation.

If you do not press YES or NO, the system will exit to the main screen and continue operation within approximately 10 seconds.

WARNING: Do not press YES unless the model is turned off or the model is secured.

Monitor

The Monitor screen displays the servo positions for each channel graphically and numerically. This is useful to verify programming functions, trim settings, mix directions, etc. The numeric value is directly relative to the travel adjust and mix values (e.g., 100% travel adjust equals 100% value in the Monitor).

X-Plus Monitor

Use of the X-Plus Monitor requires X-Plus to be active. The X-Plus Monitor screen displays the output position for each X-Plus channel graphically and numerically. This is useful to verify programming functions, trim settings, mix directions, etc. The numeric value is directly relative to the travel adjust and mix values (e.g., 100% travel adjust equals 100% value in the X-Plus Monitor). The X-Plus Monitor shows the additional channels and requires servos which can be connected to the optional X-Plus module and an X-Plus-capable receiver. X+1 and X+2 channels also serve as the monitor for channels 11 and 12 on a 12 channel receiver.

CAUTION: Do NOT connect throttle or any primary control sur face to the X-Plus Module.

3. Press the BACK button to save the Pitch Curves and return to the Function List.

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:

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 overdriving servos by limiting servo travel if the sum of your cyclic and pitch inputs exceed 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 5 rates are available, depending on the switch assigned). Make sure the gyro operates correctly and compensates in the correct direction.

Governor

The governor function is used to set the rotor head speed when used with a governor installed in the helicopter. The governor onboard will control the engine RPM to maintain the head speed desired. You can program values for each switch position or flight mode. RPM values can be programmed in 0.5% steps.

To Program the Governor Function:

1. Access the Governor menu option.
2. Program the RPM values by rotating the scroll wheel to the desired value.
3. Press the scroll wheel and rotate it to the desired value. Press the scroll wheel again to save the value.

IMPORTANT: The value in the display is the corrected value. 0% is 1.5ms or OFF for most governors. Repeat this for all governor settings.

1. Assign the output channel for the Governor. The Governor and the Gyro must be on different channels. We recommend using AUX2 for the Governor output channel.
2. Select a switch to control the Governor.
3. Press the BACK button to save the selections and return to the Function List.

Tail Curve

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. See Pitch Curve for more information on programming curves.

Mixing

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 overdriving 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.

Sailplane 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.

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.

Wing

• 1 Servo
• 2 Aileron*
• 2 Aileron 1 Flap*
- 2 Aileron 2 Flap*
• 4 Aileron 2 Flap*

Tail

- Normal

• V-Tail A**

• V-Tail B**

Motor

- Inhibit

- Assign to a Switch (optional)

Refer to community.spektrumrc.com for more information about new DX18 AirWare updates to support these options.

* Selection of multiple ailerons activates the Differential menu option.
** Selection of either of these activates the V-Tail Differential menu option.

Image Selection

Press NEXT to select the sailplane image. Highlight and select the image on screen, then use the roller to select the image desired. Press the roller to select.

Camber Preset

Camber Preset is only available when 2 or 4 aileron wing type is selected in Sailplane Type. The Camber Preset function enables you to program the ailerons, fl aps, wing tips and elevator for a specifi c 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.

Camber System

Camber System is only available when 2 or 4 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.

SAIL Mixing

For each of these mixes, you can program each fl ight mode with different mix values or at 0% if no mix is desired for that specific fl ight 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 a 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 fl ight 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 fl ight mode.

Aileron to Flap

The Aileron to Flap mix allows the entire trailing edge of the wing (aileron and fl ap) to operate as ailerons. When the mix is active, the fl aps move with the ailerons.

Elevator to Flap

Elevator to Flap mix creates additional lift, allowing a tighter turn. The entire trailing edge of the wing (aileron and fl ap) operate as fl aps (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 fl ap deployment, decreases over the next 40%, then remains the same from 60 to 100% of fl ap travel.

For sailplanes with ailerons/tips/fl aps, 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.

Receiver Installation

For optimum RF link performance, mount the main receiver and remote antennas in an orientation that allows for the best possible signal reception when the aircraft is in all possible attitudes and positions. Where supplied with the transmitter, install the primary receiver in your model. Put the primary receiver in protective foam and install the receiver in the model using rubber bands or hook-and-loop straps. Use thick double-sided foam tape to install the primary receiver in electric airplanes or helicopters.

Mount each remote receiver at least 2 inches (51 mm) away from the primary receiver, primary antenna and each other using double-sided foam tape. Orient the antennas perpendicular to each other; typically one vertical and one horizontal (see manufacturer's receiver installation instructions). This gives tremendous improvements in path diversity as each receiver can "see" a different RF environment. This is key to maintaining a solid RF link, especially in aircraft that have substantial conductive materials (e.g., larger gas engines, carbon fiber, pipes, etc.), which can weaken or block the signal.

In airplanes, we recommend mounting the primary receiver in the center of the fuselage on the servo tray and the remote receivers on the side of the fuselage or in the turtle deck (space behind the canopy and in front of the vertical stabilizer).

In helicopters, install receivers in the radio tray, where there is usually suffi cient room for receiver separation. Where there is not suffi cient room, install a receiver on an external receiver mount made of clear plastic.

NOTICE: The DSMX DX18 is compatible with all current Spe-ktrum DSM2 and DSMX aircraft receivers, but NOT compatible with the original DSM AR6000 receiver.

Power System Requirements

Set up and operate a model so power to the receiver is NEVER interrupted while fl ying. This is especially critical on giant-scale models that use several high-torque or high-current servos. Power systems unable to provide minimum receiver voltage in fl ight are the number-one cause of in-fl ight failures. Some components that cause a receiver to have too little power supply include:

• Receiver battery (number of cells, capacity, cell type, state of charge)
• Switch harness
• Battery leads
  • Regulator (where used)
  • Power bus (where used)

A Spektrum receiver's minimum operational voltage is 3.5 volts. This battery charge capacity compensates for discharge during flight or for flight loads larger than ground test loads.

CAUTION: We recommend that you DO NOT fly a model with battery charges at less than 5.3-volts.

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.

PHYSICAL TRANSMITTER ADJUSTMENTS

Mode Conversion

You can perform mode changes in the System Settings screen. However, if you desire to change modes between 1 and 2 or between 3 and 4, please contact Horizon Hobby for assistance due to requirements for changing gimbals.

Adjust Stick Tension

Adjust stick tension using the screws on the stick gimbals through holes in the back of the transmitter.

1. Remove rubber plugs from holes marked with a vertical arrow or a horizontal arrow.
2. Turn the screws in these holes a small amount using a small Phillips screwdriver to adjust tension on the vertical and horizontal gimbals.

NOTICE: Always do a test of stick tension while turning these screws to ensure stick tension is not too loose or too tight.

Tightening a screw too much can damage a spring. Loosening a screw too much can let a spring fall off and cause a short-circuit in the transmitter.

CAUTION: Always power off the transmitter, disconnect and remove the battery before adjusting stick tension or straps. Not doing so could result in property damage or

Control Stick Length Adjustment

1. Adjust control stick length using a 2mm Allen wrench.
2. Turn the setscrew in the stick counterclockwise to loosen it. Make the stick shorter by turning it clockwise or longer by turning it counterclockwise.
3. After adjustment of stick length, tighten the setscrew.

Adjust Throttle Friction Straps

• Pull up the top of the rear grip on the back of the transmitter to adjust the friction strip on the throttle gimbal. Only the top of the grip must be pulled up to access the adjustment screw, the entire grip does not need to be removed.
• Use a small Phillips screwdriver to tighten or loosen the screw for friction strip.

- Reinstall the top of the rear grip after completing the adjustment as desired.

NOTICE: Always do a test of stick tension while turning these screws to ensure stick tension is not too loose or too tight. Tightening a screw too much can damage a spring. Loosening a screw too much can let a spring fall off and a cause short-circuit in the transmitter.

Throttle Ratchet Strip Installation

The transmitter is manufactured with a smooth friction strip and the included optional ratchet strip may be installed if desired.

CAUTION: Always power off the transmitter, disconnect and remove the battery before opening the transmitter. Not doing so could result in property damage or injury.

1. Remove the battery door and disconnect the battery from your transmitter.
2. Carefully pull up the top of the left and right rear hand grips on the back of the transmitter to expose the 2 case screws.
   Tip: Only the top portion of the grip needs to be pulled back, the entire grip does not need to be removed to access the case screws.

3. Carefully remove and keep 4 screws from the back of the transmitter (2 in lower corners and 2 under the back hand grips).

4. Carefully open the transmitter case so no wires are stretched or pulled.

5. Remove and keep 2 screws from the installed throttle ratchet strip.
6. Do not remove grease from plastic part under the strip.
7. Attach the strip to the gimbal using the 2 screws.
8. Tighten the spring tension screw to get desired stick tension.

CAUTION: Make sure no wires or components are pinched or damaged while installing the back cover.

1. Carefully close the transmitter case using the 4 screws and re-install the hand grips.

2. Connect the battery to your transmitter.
