Binding Procedure

Follow these steps to bind your Mobula6 to your Frsky transmitter:

1. Power on the Mobula6. The red LED on the flight controller will blink slowly.
2. Press the BIND button on the flight controller. The red LED will become solid, indicating it is in bind mode.
3. Alternative Bind Method: Connect the drone via USB to your computer. Open Betaflight Configurator, navigate to the CLI tab and type `bind_rx`, or go to the Receiver tab and click "Bind Receiver". The red LED will turn solid.
4. On your Frsky transmitter (e.g., Taranis), go to the SETUP MENU and select BIND OPTION. Choose the receiver mode: D16 for Frsky_X or D8 for Frsky_D (D8 mode is recommended).
5. Initiate binding on the transmitter by pressing the [Bind] button. The red LED on the flight controller will blink slowly, then turn solid once binding is successful.

Receiver Configuration in Betaflight:

• In Betaflight Configurator, go to the Configuration tab.
• Set Receiver Mode to "SPI RX Support".
• Select "FRSKY_X" for FRSKY D16 MODE or "FRSKY_D" for FRSKY D8 MODE.
• Do not enable Serial RX, as the integrated SPI BUS Receiver is used.

Diagram Description: Shows the Taranis transmitter's BIND OPTION screen with mode selection (D16/D8) and the Betaflight Configurator's Receiver tab with SPI RX Support and FRSKY_D provider selected.

Arming/Disarming the Motor

The default switch for arming/disarming is AUX1 (Channel 5). This can be customized in Betaflight Configurator.

1. In Betaflight Configurator, go to the Modes tab.
2. Assign a switch (e.g., SA or SB on your transmitter) to the ARM function on AUX1 (Channel 5).
3. Ensure your transmitter's channel map matches the default TAER1234 for the Mobula6 Frsky version.
4. Toggle the AUX1 switch. The green LED on the flight controller will become solid, indicating the motors are armed. "Armed" will also appear on your FPV display.
5. Always keep the Mobula6 level before arming.

VTX Bands and Channels Setup

The VTX table lists available bands and channels. You can switch VTX channels using two methods:

• Method 1 (CLI Command): Connect via Betaflight CLI and type `set vtx_band=5` and `set vtx_channel=4`, then `save`.
• Method 2 (OSD Menu): Disarm the drone. Move the transmitter sticks (THR MID + YAW LEFT + PITCH UP) to enter the OSD Menu. Navigate to Features, then VTX SA to set the VTX Band and Channel.

Diagram Description: Displays the VTX table with bands (BOSCAM_A-F, FATSHARK, RACERBAND, LOWRACE) and their corresponding channels and frequencies. It also shows the OSD menu navigation for VTX settings.

ESC Check and Firmware Update

To check ESC status or flash firmware:

1. Download the latest BLHeliSuite from mediafire.com/folder/dx6kfaasyo241/BLHeliSuite.
2. Connect the flight controller to your computer via USB.
3. Open Device Manager to ensure the COM port number is below 255. Adjust if necessary.
4. Open BLHeliSuite. Select "SILABS BLHeli Bootloader (Cleanflight)" from the top tabs.
5. Choose the correct COM port and click "Connect".
6. You can flash new BLHeli_S firmware; the target is "O-H-05".

Diagram Description: Shows the BLHeliSuite interface for ESC setup, including firmware flashing options, ESC selection, and motor configuration settings like Startup Power, Motor Direction, and Motor Timing. It also shows the Device Manager window for COM port settings.

Mixer Type and ESC/Motor Protocol

• Mixer: Quad X
• Motor Direction: Reversed (can be changed in BLHeliSuite)
• ESC/Motor Protocol: DSHOT600
• MOTOR_STOP: Enabled (motors do not spin when armed)
• Disarm motors after set delay: Configurable (requires MOTOR_STOP feature)
• Motor Idle Throttle Value: Configurable

Diagram Description: Illustrates the Betaflight Configurator settings for Mixer (Quad X), Motor Direction (Reversed), ESC/Motor Protocol (DSHOT600), MOTOR_STOP, and other ESC features.

Default PID Settings for Betaflight 4.3.0

The following are the default PID settings for the Mobula6 V2.0:

Additional settings include Feedforward (25), Averaging (15), Jitter Reduction (OFF), Smoothness (90), Anti Gravity (Gain 3.5), I Term Relax (Cutoff 15), and Dynamic Damping (Gain 37, Advance 20).

Flight Controller Firmware Update

To update the flight controller firmware:

1. Install the latest STM32 Virtual COM Port Driver from st.com/web/en/catalog/tools/PF257938.
2. Install the STM BOOTLOAD Driver (STM Device in DFU MODE).
3. Open Betaflight Configurator and select the firmware target "Crazybee F4 FR" and the desired firmware version.
4. Enter DFU Mode:
   • Method 1: Solder the boot pad and connect the USB cable.
   • Method 2: Load Betaflight firmware and click "Flash". The FC will enter DFU Mode automatically.
5. Use Zadig tools to replace the drivers from STM32 Bootloader to WINUSB Driver.
6. Reconnect the flight controller after driver replacement and open Betaflight Configurator to load and flash the firmware.

"Flip Over After Crash" Procedure

This feature allows you to flip your drone back upright after a crash.

1. In Betaflight Configurator, go to the Modes tab.
2. Assign a switch (default is AUX4/Channel 8) to activate the "Flip" function.
3. To use the feature:
   • The drone is in a crashed state.
   • Disarm the motors.
   • Activate the "Flip over" function using your assigned switch.
   • Arm the motors again.
   • Move the transmitter stick to flip the quad.
