7.5 Fail safe

The Failsafe function can be set in the following three ways:

• Set to disable the signal output of i-BUS-out and PPM protocol interfaces in case of out-of-control, i.e., no output at i-BUS-out & PPM interfaces in case of losing control.
• Set failsafe values channel by channel: Free/Fixed value/Hold.
• [Set all fixed value channels], namely, you can set the output values of all channels controlled by a control to the current value, and this value will be output when the system is losing control.

Failsafe Test Function

Note: Gas-powered models are slightly different with Battery Powered models when it comes to failsafe setup.

Gas-powered: It is recommended to set failsafe setting as if the vehicle’s brake state, that is, set the throttle channel output value of the vehicle when subjected to brake as the failsafe value. The braking effect can be customized accordingly.

Battery Powered:

1. It is recommended that the failsafe is set to Free. In case of out-of-control, it will enter braking state when ESC does not received signals.
2. It is also possible to set the failsafe settingas if the vehicle’s brake state. Same as the gaspowerd.

• Some ESCs also use breaking as reverse, make sure to check this with your model.

7.6 Servos Frequency
This function is used to select the frequency of channel data PWM signals. The function includes analog servo (95 Hz), digital servo (380 Hz), and custom frequency.
You can select or set the correct output frequency value according to the servo used.
By default, the system adopts the digital servo. The custom frequency adjustment range is 50-400 Hz.

The servos frequency varies slightly with the connected receivers.

For the Enhanced Edition Receiver
[SR]: One of the specifications in the servo frequency (PWM frequency is 833 Hz).
[SFR]: One of the specifications in the servo frequency (PWM frequency is 1000 Hz).

Note: the conventional servo response speed (PWM frequency) is 50-400 Hz.
The delay of the whole system will be greatly improved when SR and SFR are selected. Make sure that the adapted servo supports the corresponding frequency. Otherwise, it may cause the servo not to work properly or even damage the servo.

7.7 i-BUS2 Setup

This function is used to set up the i-BUS2 devices. For details, see 6.26 i-BUS2 section.

7.8 i-BUS Setup

This function is used to set up the i-BUS expansion module.

The i-BUS function is mainly used for servo expansion. If a cable is too short or the number of servos exceeds the outputs for the receiver, the i-BUS serial bus receiver provides a convenient option for expansion. When using the i-BUS serial bus receiver, make sure that it is powered separately to ensure that servos have sufficient power.

7.9 Config PWM Converter
This function allows you to configure the corresponding receiver to a PWM converter.
After the setting is successful, the receiver is used as a PWM converter, and the interfaces output PWM signals.

Note: This function is not available for all receivers. For the classic receiver, only the FGr4 and FTr10 receivers are availabe.

• The receiver which is set as the PWM converter can be converted into a receiver by rebinding the transmitter, and then used normally as a receiver after successfully rebinding the transmitter.

[i-BUS To PWM]: This feature is adapted to classic version or enhanced version receivers to config as PWM converter. For the classic version receivers, after it is set as a PWM converter, its SENS interface is connected to the interface of the receiver outputting i-BUS or i-BUS out. For the enhanced version receivers, after it is set as a PWM converter, its NPA interface is connected. [i-BUS2 To PWM]: This feature is adapted to enhanced version receivers to config as PWM converter. After it is set as a PWM converter, its NPA interface is connected the interface of the receiver outputting i-BUS2. And you can set related parameters through [i-BUS2], refer to 6.26 i-BUS2 section.

7.10 RSSI Output Setup

7.11 RX Battery Monitor
This function is used to detect the voltage status of the receiver or corresponding Sensor battery.

Notes:

1. [ESC Power] is only applicable for Hobbywing XERUN AXE R2 ESC.
2. When multiple XERUN AXE R2 ESCs are connected, the setting is for the first ESC connected.
3. [Internal Voltage] is corresponding to the voltage of the receiver; [External Sensor Voltage] is corresponding to the voltage detected by the FS-CVT01 sensor; [BVD Voltage] is corresponding to the voltage detected through BVD function; [ESC Power] is corresponding to the power of XERUN AXE R2 ESC.

7.12 Range Test
This function is used to test whether wireless communication between the transmitter and the receiver is normal.

As the actual remote control distance between transmitter and receiver is far, it is hard to test whether the radio frequency is normal by controlling a distance of several hundred meters between the transmitter and receiver in practice. Theoretically, the remote control distance in this function will be reduced to 30-40 meters. So, you can test whether wireless communication between the transmitter and the receiver is normal at a close distance when the function is enabled. This can save testing time.

Setup:

1. Make sure the transmitter and receiver are bound.

2. Enter the [Range Test] menu and press the SW1-R button.

3. One person stands in place with the model in hand, and the other person holds the transmitter and gradually moves away to 30-40 meters and walks around with this distance as a radius centered on this model.
   • Please make sure the transmitter is installed with phone holder, with use of the standard version firmware.
   • Make sure that the transmitter antenna is unobstructed and that there are no objects or sources of interference between the transmitter and the receiver.

4. Check the RSSI on the transmitter. If the signal strength is high and stable, it means that the radio frequency of this system works normally.

7.13 BVD Voltage Calibration
The BVD voltage is calibrated before delivery from the factory. This function can be used when there is an excessive deviation between the detected and actual voltages.
The BVD voltage detection range is from 0 to 100V.
Note: This function is not available for classic version receivers. Pay attention to correctly connect the BVD cable to the anode and cathode terminals of the battery.
The connection diagram is as follows.

Setup:
Connect the BVD detection line correctly before setting, and then perform calibration.
Note: please refer to the voltage value of multimeter for calibration.
1. Click [BVD Voltage Calibration] to enter the function setting interface.
2. Click “+” or “-” to change the battery voltage value as needed.
3. Click [Calibration]. After successful calibration, click “YES” in the pop- up window reminder.

Note: When not adjusted, the [Battery voltage] value is displayed the voltage value in realtime, if set, the edited value is displayed.

7.14 Low Signal Alarm

This function is used to enable or disable the low signal alarm function.
[Low Signal Alarm]: If checked, the system will alarm automatically if the signal strength of the receiver is lower than 30.

7.15 Update Receiver Firmware
After the transmitter has updated the firmware, and at the time, it can not bind with the receiver, then the receiver firmware is needed to be updated.

Setup:
Touch [Update Receiver]:

• Some receivers such as GMR need to be updated with “Flysky Assistant”.
• If the transmitter has successfully coded and the connection is established, if the receiver is the latest version, a pop-up prompt will appear [The current version is the new version, no upgrade is required! ]. If the receiver is an old version, a pop-up prompt [Are you sure to update the receiver? ]. Click [OK] to update the receiver;
• If the receiver and the transmitter are not connected, then enter the Select Receiver interface, check the receiver to be connected and pop up a prompt [Please connect XX or enable XX enter the mandatory update mode]. Click [OK]!

After entering the update state, When the progress is 100%, it indicates the update is successful.

Note: You must update the transmitter’s firmware before updating the receiver’s firmware.

The steps of the forced update of the receiver are as follows:

1. Press and hold the Bind key on the receiver over ten senconds while powering on the receiver, then release the Bind key after the receriver LED works in flashthree- one-off state repeatedly.
   Or Power on the receiver first, then press and hold the BIND button for more than 10 seconds, the LED of the receiver will be in a state of three-flash- one-off, then release the BIND button.

2. Power on the transmitter and select [Update Receiver]. Click the corresponding receiver. Select “OK” on the pop-up box. Click [Update] to enter the update state.

3. When the update has finished, the receiver LED flashes slowly.
