The Happymodel Mobula 7 is a 1-2S Frsky Micro brushless FPV racer drone, designed for both beginners and experienced pilots. This compact drone comes with a basic version package that includes a 75mm Brushless Bwhoop75 Frame, a Crazybee F4 PRO Frsky receiver, four SE0802 KV16000 Motors, one set of 40mm propellers (4cw+4ccw), an AIO Camera & VTX, a buzzer, four 3.8v 250mah 30C/60C batteries, a USB Lipo/LIHV Charger, a propeller disassemble tool, and a screwdriver. A standard version is also available, which adds a 1506 6-way Lipo/LIHV charger.

Function Description:

The Mobula 7 is an FPV racing drone, meaning it is designed for agile flight and real-time video transmission to a pilot's goggles or monitor. Its brushless motors provide efficient and powerful thrust, while the integrated Frsky receiver allows for control with compatible Frsky transmitters. The AIO Camera & VTX (Video Transmitter) captures and transmits the FPV feed. The drone's small size makes it suitable for indoor and outdoor flying in confined spaces.

Important Technical Specifications:

• Flight Controller: Crazybee F4 PRO Frsky receiver (integrated SPI BUS Receiver).
• Motors: SE0802 KV16000 Brushless Motors.
• Frame: 75mm Brushless Bwhoop75 Frame.
• Propellers: 40mm (Props IN configuration: CW on M1/M4, CCW on M2/M3).
• Batteries: 3.8v 250mah 30C/60C (1-2S compatible).
• VTX (Video Transmitter): Integrated with the AIO Camera, supporting SmartAudio for channel and band changes.
• Receiver: SPI RX support, compatible with Frsky D16 (FRSKY_X provider) and D8 (FRSKY_D provider) modes.
• ESC Protocol: DSHOT600.
• Firmware: Betaflight (recommended 10.4.0 or 10.4.1 configurator, or update to V4.0.0 or latest for 10.5.1 configurator). BLHeli_S for ESCs (Target: S-H-50).

Usage Features:

Receiver Configuration:

To set up the receiver, navigate to the "Configuration" tab in Betaflight Configurator. Select "SPI RX Support" for the Receiver mode. For Frsky D16 mode, choose "FRSKY_X Provider," and for Frsky D8 mode, select "FRSKY_D Provider." It's crucial not to enable "Serial RX" as the Crazybee Flight controller has an integrated SPI BUS Receiver.

Binding Procedure:

1. Connect the Mobula 7 to your computer and open Betaflight Configurator.
2. Go to the CLI Command tab and type "bind_rx". The two red and two white LEDs on the flight controller will become solid, indicating binding mode. If using Betaflight firmware 4.0.x, the bind code is "bind_rx_spi," or you can use the physical bind button after powering up the Mobula 7.
3. Turn on your Frsky Taranis transmitter. Navigate to the "BIND OPTION" in the "SETUP MENU." Select "D8" for the receiver mode (default factory mode). If you intend to use D16 mode, change the "SPI Bus Receiver Provider" to "Frsky_X" (though this is not suggested in the manual).
4. Press "ENT [Bind]" on your transmitter to initiate binding. The LED Combo (two red and two white LEDs) on the flight controller will blink slowly, indicating successful binding. Once bound, the LEDs will become solid again, signifying normal operation.

Arming/Disarming the Motor:

1. The default arm/disarm switch is AUX1 (Channel 5). This can be customized in Betaflight Configurator under the "Modes" tab.
2. On your Frsky transmitter (e.g., X9D+), go to the "MIXER" interface. Assign a switch (e.g., "SA" or "SB") to Ch5 for arming/disarming.
3. The default channel map for the Mobula 7 Frsky version is TAER1234. Ensure your transmitter's channel map matches this to avoid arming issues. Toggling the AUX1 switch will make the green LED on the flight controller solid, indicating the motor is armed. "Armed" will also display on your FPV goggles or monitor. Always ensure the Mobula 7 is level before arming.

VTX Bands and Channels Setup:

The VTX (Video Transmitter) has 8 channels across 5 bands.

• LED Indicators: Blue LED 1 and Red LED 1 indicate 5865MHZ (Band1, CH1). Blue LED 1 and Red LED 2 indicate 5845MHZ (Band1, CH2). Blue LED 6 is the last blue LED that won't light up. Red LED 8 indicates 3.3-5.5V GND.
• Switching Channels:
  1. Button Press: Short press the button to select the VTX channel. Press and hold the button to select the VTX band. Note that changes made this way are not saved after power-off.
  2. Betaflight CLI: Use commands like set vtx_band=3, set vtx_channel=1, set vtx_freq=5705, followed by save. Ensure vtx_freq matches the vtx_band and vtx_channel as per the VTX Channel list. For example, vtx_freq=5732 requires vtx_band=5 and vtx_channel=3.
  3. SmartAudio (OSD Menu): Enable SmartAudio for UART1. Then, 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.

Mixer Type and ESC/Motor Protocol:

The Mobula 7 uses a "Quad X" mixer type. The motor direction is reversed.

• Props IN Configuration: CW propellers on M1 and M4 motors. CCW propellers on M2 and M3 motors.
• ESC/Motor Features: DSHOT600 protocol. "MOTOR_STOP" prevents motors from spinning when armed. "Disarm motors regardless of throttle value" disarms motors via AUX channel if configured. "Disarm motors after set delay" disarms motors after a specified time (requires MOTOR_STOP). "Motor Idle Throttle Value" sets the idle throttle percentage.

Maintenance Features:

ESC Check and Flash Firmware:

1. Download BLHeliSuite: Obtain the latest version from mediafire.com/folder/dx6kfaasyo241/BLHeliSuite.
2. Connect Flight Controller: Connect the Crazybee F4 PRO flight controller to your computer.
3. Device Manager Check: Open your computer's Device Manager and verify that the COM port Serial Number for the flight controller is under 255. If it's higher, you may need to change it in the port settings to ensure BLHeliSuite can connect.
4. Open BLHeliSuite: Select "SILABS BLHeli Bootloader (Cleanflight)" from the third tab. Choose the correct Serial COM port and click "Connect." You can also flash the new BLHeli_s firmware, with the target being "S-H-50."

Flight Controller Firmware Update:

1. Install STM32 Virtual COM Port Driver: Download and install the driver from st.com/web/en/catalog/tools/PF257938.
2. Install STM BOOTLOAD Driver: Install the STM Device in DFU MODE driver.
3. Betaflight Configurator: Open Betaflight Configurator and select the firmware target "CrazybeeF4FR," then choose the firmware version.
4. DFU Mode Entry:
   • Solder the boot pad and then plug the USB into the computer.
   • Load Betaflight firmware and hit "flash," which will automatically put the device into DFU Mode.
5. Zadig Tools: Use Zadig tools to replace the drivers from "STM32 Bootloader" to "WINUSB Driver."
6. Reconnect and Flash: Reconnect the flight controller to the computer after replacing the driver. Open Betaflight Configurator, load the firmware, and flash.

Important Notes:

• Always use Betaflight Configurator 10.4.0 or 10.4.1 for setting up the Mobula 7 if using older firmware. If you wish to use 10.5.1 Configurator, update the Betaflight firmware to V4.0.0 or later.
• Do not disable MSP on the first serial port unless you know what you are doing, as it may require re-flashing and erasing your configuration.
• Ensure the Mobula 7 is level before arming to prevent unexpected motor behavior.
• Be careful and enjoy your flight!
