Spektrum DX6 Rugged 6-Channel 2.4GHz DSMR Radio System

Individual Direction Adjustments

In some cases, you may need to adjust steering directions individually. For example, if you want more travel for the left steering than the right, follow these steps:

1. Scroll to the value you wish to change and click the scroll wheel.
2. With both directions selected, move the control (throttle or steering) in the direction you want to adjust. The selection box will move in the desired direction. You do not need to hold the control in the desired direction.
3. To change the opposite direction, simply move the control in that direction.
4. Click the scroll wheel to save the selection.

Automatic Switch Selection

To easily select a switch for a function, such as a programming mix, scroll with the scroll wheel to highlight the switch selection box, then click the scroll wheel. The box around the switch should now blink. To select a switch, move the desired switch. Confirm that the switch selection displays as desired. If correct, click the scroll wheel to select this switch and complete the switch selection.

TIP: The checkmark icon indicates the current switch position.

Scrolling and clicking the scroll wheel will turn the selected box black, indicating that the value or state at that position will be active.

Tip for Switch Selection

If the system does not allow a change from "INHIBIT", it means all switches are already assigned to another function. Unassign a switch from another function to make it available for selection.

The DX6 Rugged does not allow overwriting switch assignments. If a switch is configured for a function, the switch assignment for that function must be disabled before the switch can be used for something else.

Model Selection

CAUTION: NEVER change the model in the Model Select list while a model is in operation. Changing the model memory interrupts the transmitter signal to the receiver, which can lead to loss of vehicle control, damage, or injury.

Model Select provides access to the 20 internal model memory slots.

1. Scroll to the desired model memory slot in the “Model Select” list.
2. Once the desired model slot is highlighted, click the scroll wheel once to select the model. The transmitter will return to the main screen.
3. To add a new model, scroll to the bottom of the list. You will be prompted with the “Create New Model” screen.

Model Name

Model Name allows you to assign a custom name to the current model memory. Model names can be up to 15 characters, including spaces.

Adding Letters to a Model Name:

1. Scroll to the desired character position and click the scroll wheel once. A blinking box will appear.
2. Scroll up or down until the desired character appears. Click the scroll wheel once to save the character.
3. Scroll to the next desired character position. Repeat steps 1 and 2 until the desired model name is complete.
4. Select the BACK switch to return to MENU.

Deleting Characters:

1. Press the CLEAR switch while the character is selected.
2. Press the CLEAR switch again to delete all characters to the right of the cursor.

Travel

“Travel” sets the total travel or endpoints of servo arm movement. Travel values range from 0-150% (default is 100%).

Adjusting Travel Values:

1. Scroll to the channel you wish to adjust and click the scroll wheel.
2. Scroll up or down to adjust the travel value. Click the scroll wheel to save the selection.

Sub Trim

Sub Trim adjusts the entire range of servo travel, including the center and endpoints.

CAUTION: Use only small values for Sub Trim. Using full servo travel with larger values may affect this range.

Reverse

The “Reverse” menu allows you to reverse channel direction. For example, if the steering servo moves left, reversing the channel will make the servo move right.

Reversing a Channel Direction:

1. Scroll to “Travel” and click the scroll wheel. Scroll up or down until “Reverse” appears and click the scroll wheel again to save the selection.
2. Scroll to the channel you wish to reverse and click the scroll wheel.

If you reverse the throttle channel, a confirmation screen will appear. Select “YES” to reverse the channel. A second screen will remind you to bind your transmitter and receiver.

CAUTION: Always re-bind the transmitter and receiver after reversing the throttle channel. Failure to do so may cause the throttle to move to full throttle when failsafe activates.

Always perform a control test after making adjustments to confirm the vehicle responds correctly.

CAUTION: Always re-bind the transmitter and receiver after adjusting servos to set failsafe positions.

Speed

The “Speed” menu allows you to slow down the response time on any individual channel. Speed is adjustable from 100% down to 1%.

Adjusting Speed:

1. Scroll to the channel you wish to adjust and click the scroll wheel.
2. Scroll up or down to adjust the speed and click the scroll wheel to save the selection.
3. Select a switch to enable/disable the function. If the switch is set to “ON”, the value for this function will always be active.

Rates

“Rates” allows the driver to reduce the travel (0-100%) of steering, throttle, or brakes using a trim switch. With the “Override” option, drivers can select a different value (0-125%) while the assigned trim switch is pressed. This is particularly helpful for drivers on oval tracks who may want to program minimal steering input for less sensitivity during a race, but maximum steering angle for maneuvering out of an accident or for tracking on the track.

Adjusting Rate Values:

1. Scroll to “Steering” and click the scroll wheel to select between Steering, Throttle, or Brake.
2. Scroll up or down to adjust the rate value. Click the scroll wheel to save the selection.
3. Set the switch settings to “On” to activate rates, and select “Inh” to disable rates.
4. Select an “Override” rate and switch.
5. Select the OTF (On-The-Fly) trimmer to be used for spontaneous rate adjustments.

TIP: For override to function, it must be assigned to a switch or trimmer. The default position for this function is inhibited.

Exponential

The Exponential (Expo) function affects the response speed of steering, throttle, and/or brakes. For example, a positive steering expo value reduces steering sensitivity around neutral, making it easier to drive straight at high speeds, while still allowing for maximum turning radius. While sensitivity is reduced around neutral with positive expo, it increases sensitivity near the end of travel.

Adjusting Expo Values:

1. Select Throttle or Steering.
2. Scroll up or down to adjust the rate value.
3. Click the scroll wheel to save the selection.
4. Select an OTF switch to activate the exponential.

IMPORTANT: Both positive and negative expo values are available. A positive expo value makes the center less sensitive (most desired), while a negative expo value increases sensitivity around the center (not typically used).

Timer

The DX6 Rugged timer function allows you to program a countdown timer and a stopwatch (“count up” timer) that will be displayed on the main screen. An alarm will sound when the programmed time is reached. You can program the timer to start with the use of the assigned switch position, or automatically when the throttle moves past the pre-programmed position.

Bind / Frame Rate

NOTICE: After changing the frame rate, re-bind the system.

Three frame rates are available for compatibility with all servo types:

• 11 ms: Offers good response speeds and is compatible with most digital and analog servos (this is the default). Works with DSMR surface receivers.
• 16.5 ms: Required for older analog servos. Works with DSM2 surface receivers.
• 22 ms: Required for older analog servos. Works with DSMR receivers.

TIP: You should always select the fastest response speed the servo can handle. This provides the least latency and fastest reaction. If the frame rate is not compatible with the servo, the servo will move erratically or, in some cases, not at all. If this occurs, change the frame rate to the next highest value.

Failsafe

In the unlikely event that the radio link is lost during operation, the receiver will move the throttle servo to its pre-programmed failsafe position (typically full brake) and all other channels will have no servo output. The throttle failsafe position is set during binding. If the receiver is powered on before the transmitter, it will enter failsafe mode, moving the throttle servo to its set failsafe position. When the transmitter is powered on, normal operation resumes.

IMPORTANT: Failsafe is only activated in the event of signal loss from the transmitter. Failsafe is NOT activated if the receiver battery voltage drops below the recommended minimum or if power is lost to the receiver.

NOTICE: AVC receivers must be calibrated after binding for correct operation.

Binding

Binding is the process by which the receiver learns the transmitter’s unique code, known as a GUID (Globally Unique Identifier), and stores the failsafe values. When a receiver is bound to a transmitter/model memory, it will only respond to that specific transmitter/model memory.

Binding Procedure:

1. Put the receiver into bind mode. The LED on the receiver will begin to flash.
2. Turn on the transmitter.
3. Select the model memory you wish to bind to.
4. Select “Bind” from the menu list.
5. Move the throttle stick to the desired failsafe position.

NOTICE: The throttle stick must remain in the failsafe position until binding is complete.

1. Scroll to “Bind” and click the scroll wheel. The orange LED on top of the transmitter will flash.
2. When the binding process is complete, the transmitter and receiver LEDs will stop flashing and remain solid orange.
3. Remove the bind plug from the receiver and store it in a safe place.

NOTICE: Always remove the bind plug from the receiver once binding is complete. If left in, the receiver will enter bind mode the next time it is powered on.

Combinations

Combinations can link two servo outputs to one control input. The DX6 Rugged comes pre-programmed with steering combinations and a programmable combination (Mix 0). AUX channels can only be assigned to one combination at a time. If AUX1, 2, or 3 is assigned to another combination, that channel will not be available as a slave.

Channel option is not available. Channels AUX 1 and 2 are not available for use in combinations when the AVC menu is active in the transmitter.

AVC Programming Menu

The DX6 Rugged includes a menu specifically for AVC operation. This menu manages the operation of AUX 1 and AUX 2, adjusting them for use with AVC technology. The AVC menu also controls “Priority” functions.

To Activate the AVC Menu:

1. Select AVC from the main menu.
2. Select “Switch” and use the scroll wheel to select “On” to activate the AVC menu.
3. Adjust the Gain and Priority values to suit your vehicle.
4. For fine-tuning individual values during use without accessing the programming menu, assign a trimmer to the OTF (On-The-Fly) function for each AVC value.

Click the arrow next to the switch selection to assign the trimmer for increasing or decreasing the gain from the set value.

TIP: Trimmers can only be assigned to an OTF function. Gain values for steering and throttle cannot be adjusted via a trimmer switch.

TIP: For receivers without AVC, leave the AVC menu in the DX6 Rugged inhibited (INH).

To update, the transmitter must be registered. Updates require a USB-C data cable (not included) and a PC. The tool holder (B) is designed for storing 4-way wrenches.

Standard Wheel Conversion

1. Remove the steering wheel using a 1.5mm hex driver.
2. Reinstall the steering wheel.

AVC Parameters

What is Gain?

A gain value of 0 will result in zero electronic corrections, while a gain of 100 will result in extensive corrections in an effort to maintain a straight line.

• Steering Gain tells the receiver how much assistance the steering needs when the vehicle is out of control.
• Throttle Gain tells the receiver how much assistance is needed with throttle when the vehicle is out of control.

Default gain values are 50. It is recommended to adjust gain values by 5-point increments. Make smaller adjustments to the settings as you achieve desired performance. Avoid large gain adjustments between tests.

What is Priority?

Priority tells the transmitter how much you want to override the electronic stability with your control inputs. Low priority means the AVC makes steering corrections when you turn the wheel to full lock. High priority will reduce AVC the more you turn the wheel.

The default priority value is 100. This means that if you turn the steering wheel to its limit, the gain will be reduced to zero. This value will work well for the majority of drivers.

What is Heading Hold?

Heading Hold will maintain the vehicle’s selected direction. It is normal for the wheels to steer in the same direction they were last pointed. If a vehicle with AVC technology is lifted and spun side-to-side, the wheels will move in an effort to return to the original direction of travel. While driving, Heading Hold only functions when the steering wheel is kept straight. As soon as you turn the wheel, Heading Hold disengages. When the steering wheel returns to center, Heading Hold will re-engage.

AVC Tuning Procedure

1. With the transmitter and receiver already bound and properly calibrated, turn on the transmitter and vehicle.
2. Apply throttle, but do not turn the steering wheel, and observe how well the vehicle maintains a straight line at high speeds.
   • If the vehicle does not make sufficient steering corrections to maintain a straight line, increase the steering gain.
   • If the vehicle drifts due to wheel spin, increase the throttle gain.
   • If the vehicle oscillates (flutters), decrease the steering gain.
   • Do not exceed the maximum gain values that prevent oscillation at high speeds.
3. Drive the vehicle through accelerated turns and observe its reaction.
   • If the vehicle slows down at the start of a turn, decrease the throttle gain.
   • Reduce throttle gain to allow the vehicle to slide more with intentional wheel turns.
   • To improve traction in slippery conditions, increase throttle gain.
   • If the vehicle does not steer, increase priority.
   • If the vehicle oversteers, there are two possible tuning options:
     • Increasing throttle gain will help correct unwanted wheel rotation when the vehicle over-revs.
     • Decreasing priority will give the receiver more control to correct oversteer.

General Tuning Tips

NOTICE: When adjusting steering and throttle trims on your transmitter, the receiver must be powered off and then on again for the new trim settings to be saved. Otherwise, AVC will not function correctly.

Higher gain is helpful for beginner drivers, loose conditions, and vehicles with excessive power. For terrain with higher traction and increased speeds, tuning will result in lower steering gain values.

Impact of Battery Voltage

If voltage is increased, the maximum steering gain setting will need to be reduced. Simultaneously, with increased voltage, higher throttle gain will help when handling the additional power.

For example, if a 2S-equipped truck is upgraded to 3S, it may oscillate at high speeds on 3S and require a reduction in steering gain. Throttle gain will have a greater effect on 3S, so increasing throttle gain may be beneficial.

Typical Mounting

Electric Model: Mount receiver between the electronic speed controller and the battery. Connect steering servo and receiver.

Nitro Model: Mount receiver between the steering servo and the battery. Connect steering servo and throttle servo.

Receiver Compatibility

The SR515 receivers are compatible with Spektrum DSM2 and DSMR surface radio systems. They are not compatible with DSM transmitters or Spektrum aircraft systems.

Binding

The SR515 receivers must be bound to the transmitter before they will function. Binding is the process by which the receiver learns the transmitter’s unique code, allowing it to connect only to that specific transmitter.

Standard Mode:

With SmartSafe, the throttle channel is brought to its intended failsafe position (low throttle) upon signal loss, which is stored during binding. All other channels retain their last position. When the receiver regains signal from the transmitter, normal operation can resume.

Nitro Mode:

The preset failsafe is ideal for nitro/gas vehicles. With preset failsafe, all channels move to their preset failsafe positions upon signal loss, preventing the situation from becoming uncontrollable. When the receiver regains signal from the transmitter, normal operation can resume.

Standard Mode Binding:

1. Press and hold the bind button, then turn on the receiver.
2. Turn on the transmitter.
3. Release the button once the RX enters bind mode (blinking LED).
4. Put the receiver into bind mode and complete binding.

Nitro Mode Binding:

1. Press and hold the bind button, then turn on the receiver.
2. Press the Bind button until binding is complete.
3. Put the receiver into bind mode and complete binding.
4. When the LED is solid, turn off the receiver and release the bind button.

Failsafe

The failsafe position is set during binding. In the unlikely event that the radio link is lost during operation, the receiver will move all channels to their pre-programmed failsafe position.

Receiver Antenna

WARNING: Do not bend, cut, or damage the antenna wire. The antenna is a coaxial cable. If the outer jacket is damaged, the receiver will not function correctly. If the antenna is damaged in any way, replace it before using the receiver.

The SR515 receivers feature a coaxial antenna for easy mounting in almost any model. The last 32 mm (1 inch) at the tip of the antenna is the active part of the antenna; the coaxial part leading to it is merely an extension. Install the antenna so the active part is positioned as high as possible in the vehicle and is not “shadowed” by carbon fiber or metal.

The receiver case can directly accept an antenna tube, allowing for optimal and easy antenna placement (antenna tube not included). Tube size may vary; check for fit.
