2. Package Contents

The Happymodel Mobula7 1S Micro FPV Drone (BNF ELRS SPI RX version) package includes the following:

• Happymodel Mobula7 1S Micro FPV Whoop Drone (BNF ELRS SPI RX)
• Spare Propellers
• Small parts and accessories for assembly/maintenance

Note: As a Bind-N-Fly (BNF) version, this package does NOT include a remote control, FPV goggles, or flight batteries. These items must be purchased separately by the user.

3. Setup

Before your first flight, ensure you have all necessary external equipment, including a compatible ExpressLRS radio transmitter, FPV goggles, and 1S LiPo/LiHV batteries (450mAh/550mAh/650mAh recommended) with a suitable charger.

3.1. Initial Inspection

Carefully inspect the drone for any visible damage or loose connections. Ensure propellers are securely attached and free from obstruction.

3.2. Binding with Transmitter

The drone comes with a built-in 2.4G ELRS V2.0 receiver. Refer to your ELRS transmitter's manual for specific binding instructions. Generally, you will need to put both the drone (powered on) and the transmitter into binding mode. Once bound, verify control inputs in Betaflight Configurator.

3.3. Betaflight Configuration (Optional)

For advanced users or troubleshooting, connect the drone to a computer via USB and use the Betaflight Configurator software. This allows for fine-tuning flight parameters, calibrating sensors, and updating firmware.

5. Operating Instructions

The Mobula7 1S is designed for nimble and agile flight. It performs exceptionally well in tight indoor spaces due to its lightweight design and responsive motors. For outdoor flights, ensure minimal wind conditions to maintain optimal control.

5.1. Basic Flight

After binding your transmitter and powering on the drone, arm the motors using your configured switch. Gently increase throttle to lift off. Practice smooth control inputs for hovering, forward flight, and turns.

5.2. Flight Modes

The drone supports various flight modes configurable in Betaflight. Familiarize yourself with Angle mode (self-leveling) for beginners and Acro mode (manual control) for advanced maneuvers.

5.3. Turtle Mode

Turtle Mode allows the drone to flip itself over if it lands upside down. This feature is highly beneficial for FPV pilots, especially when flying in challenging environments.

6. Maintenance

Regular maintenance ensures the longevity and performance of your Mobula7 1S drone.

• Propeller Inspection: Check propellers for cracks, bends, or damage after every crash or hard landing. Replace damaged propellers immediately to prevent vibrations and loss of control.
• Motor Cleaning: Keep motors free from dirt, dust, and debris. Use compressed air or a soft brush to clean them.
• Frame Integrity: Periodically inspect the frame for any cracks or stress points. While durable, extreme impacts can cause damage.
• Battery Care: Always store LiPo/LiHV batteries at storage voltage and avoid over-discharging or over-charging.

7. Troubleshooting

If you encounter issues with your Mobula7 1S, consider the following common troubleshooting steps:

• No Power: Ensure the battery is fully charged and correctly connected. Check for any loose power cables.
• Binding Issues: Re-attempt the binding process with your transmitter. Ensure both devices are in binding mode and within range.
• Unstable Flight/Drifting: Calibrate the accelerometer in Betaflight Configurator. Check for bent propellers or damaged motors.
• No FPV Feed: Verify the Runcam Nano3 camera connection to the flight controller and ensure the OpenVTX is powered and set to the correct frequency.
