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 receiver to your transmitter before it will operate.

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

4. 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.

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

6. 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.
7. Remove the bind plug from the receiver.

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. Some receivers do not support Failsafe on throttle set to channels other than the throttle channel. These receivers will hold last command.

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 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:

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 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 advance to mid or full throttle.

IMPORTANT: Not all receivers support Preset Failsafe. Consult your receiver manual for more information.

x-PLUS™ MODULE

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 fine 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,

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.

CAUTION: Only use the included Jumpers with the X-Plus 8 module. Do not use Bind Plugs for the Jumpers.

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.

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 on fast chargers have a tendency to false peak (i.e. not fully ), which could lead to a crash.

x-Plus Channels and Failsafe

Failsafe is not supported for servos connected to the X-Plus Module. 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.

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 signals 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.

The Frame Rate menu enables you to change the frame rate and modulation mode. Select the option you wish to change and press the scroll wheel.

You must use digital servos if you select 11ms* frame rate. Analog and digital servos can be used with a 22ms frame rate.

Modulation Mode

We recommend using DSMX ^® (default) modulation mode. When DSMX is active, the transmitter operates in DSMX with DSMX receivers and DSM2* with DSM2 ^® receivers. The transmitter automatically detects DSM2 or DSMX during binding and changes the mode accordingly to match the receiver type you are using. If you select DSM2, the transmitter operates in DSM2 regardless of whether it is bound to a DSM2 or DSMX receiver.

*DSM2 is not available in the EU.

Dx20 compatibility Mode

Set DX20 compatibility to Act only if you are importing models created on or for a DX20. The DX20 compatibility mode changes channels 11 and 12 and X-Plus 1 and 2 to shared channels, and allows them to be adjusted in the X-Plus 1 and 2 settings (travel adjust, sub trim, etc.)

Leaving Compatibility Inhibited allows the DX20 to have full 20 channel control.

Frame Rate 11 ms When 11 ms is selected, digital servos must be used. Mode: DSMX XPLUS: Inh DX18 Compatibility: Act LIST NEXT

Trainer Menu Wired Trainer Wireless Trainer Trainer Alerts

▶ 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, flaps 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.

▶ 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.

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.

▶ Back Mixing

Back Mixing applies to all related servos in a multi servo Aileron/Flapped wing or a multi servo split elevator. Creating a mix to RAL (Right Aileron) or LAL (Left Aileron) will create different results and 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).

FUNCTION LIST

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.

Sequencer LIST

Su Names

1 Inh Door Cycle / Wheels 2 Inh Door Basic / Wheels 3 Inh S3A / S3B 4 Inh 4A /4B 5 Inh S5A / S5B

CAUTION: Always review the action of a sequence on the Monitor or X-Plus Monitor screen BEFORE operating the model to ensure controls act as desired. Failure to do so cause 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 LIST Switch: Inhibit Speed Forward: 5.0 Reverse: 5.0 Name A: Door Cycle (DDR) Name B: Wheels (UHL) Chan A: Inh Type A: Step Chan B: Inh Type B: Step

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.

FUNCTION LIST

ProTrim

ProTrim allows the Rates, Expo, Mixes, and Differential (Aileron, V-Tail, Rudder, Tip-Aileron, and Flap) to be adjusted by the left and/or right trims during initial trimming flights.

To setup Left or Right ProTrim:

1. Scroll to CENTER, then press the scroll wheel to zero the value of the trim in it's current position. Pressing CENTER will center the Trims and allow for further trimming even if the trims have been moved to there end points.
2. Scroll to Adjust, then press the scroll wheel to select Rates, Expo, Mixes or Differential.
3. If Rates or Expo are selected, scroll to Axis to select the axis that Pro Trim modifies. The Left /Right and Up/Down directions can be made active or Inhibited.

Because ProTrim is designed to fine tune final trims and not as a standard flight trim, it will revert back to INH after the next power cycle.

When ProTrim is Active, moving one of the trim buttons will enable a Pro Trim menu to appear on the main screen. When Pro Trim is displayed, press the scroll wheel to go directly to the Pro Trim Menu.

HELI (HELICOPTER)

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 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.

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 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.

SAIL (SAILPLANE)

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.

V-Tail Differential

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.
