4. সেটআপ

Follow these steps to prepare your Mobula7 drone for its first flight.

4.1 ব্যাটারি সংযোগ

1. Ensure the drone's power switch (if present) is in the OFF position.
2. Connect a fully charged 1S LiPo battery (450mAh, 550mAh, or 650mAh recommended) to the drone's battery connector. Ensure correct polarity.
3. Secure the battery in the designated battery tray or strap.

4.2 ExpressLRS Receiver Binding

The Mobula7 features a built-in SPI ExpressLRS 2.4GHz receiver. To bind it with your ExpressLRS compatible radio transmitter:

1. Power on the Mobula7 drone by connecting the battery. The receiver's LED should start flashing slowly.
2. Power cycle the drone three times rapidly (connect battery, disconnect, connect, disconnect, connect). After the third connection, the receiver LED should flash rapidly, indicating it is in binding mode.
3. On your ExpressLRS compatible radio transmitter, navigate to the ExpressLRS LUA script or menu and select the 'BIND' option.
4. Once bound, the receiver LED on the drone will turn solid, indicating a successful connection.
5. If binding fails, ensure your transmitter's ExpressLRS firmware version is compatible with the drone's receiver (v3.0 or newer recommended).

4.3 Betaflight Configuration (Advanced Users)

The drone comes pre-configured with Betaflight firmware CRAZYBEEF4SX1280 4.5.1. For advanced settings or troubleshooting, you can connect to Betaflight Configurator:

1. Download and install the latest Betaflight Configurator software on your computer.
2. Connect the drone to your computer using a USB-C cable.
3. Open Betaflight Configurator and click 'Connect'.
4. You can now adjust PID settings, rates, OSD elements, and other advanced parameters. সতর্কতা: Modifying settings without proper knowledge can lead to unstable flight or damage.

5. অপারেটিং নির্দেশাবলী

This section provides guidance on safely operating your Mobula7 drone.

৭.৩ ফ্লাইট-পূর্ব পরীক্ষা

• Ensure propellers are securely attached and free from damage.
• Verify battery is fully charged and securely mounted.
• কোন আলগা তার বা যন্ত্রাংশ আছে কিনা তা পরীক্ষা করুন।
• Confirm your radio transmitter is powered on and bound to the drone.
• Perform a range check in a safe area before flying.

5.2 সশস্ত্র এবং নিরস্ত্রীকরণ

The drone's motors will not spin until it is armed. Arming and disarming procedures are typically configured in Betaflight:

• অস্ত্রধারী: Move the arming switch on your transmitter to the designated arm position. The motors will typically spin slowly, indicating readiness for flight.
• নিরস্ত্রীকরণ: Move the arming switch back to the disarm position. The motors will stop spinning. In an emergency, you can also disarm by moving the throttle to zero and yawing hard left or right (check your Betaflight configuration for specific emergency disarm gestures).

৪.১ মৌলিক ফ্লাইট নিয়ন্ত্রণ

Familiarize yourself with standard quadcopter controls:

• শ্বাসনালী: Controls altitude (left stick up/down for Mode 2).
• ইয়াৰ Rotates the drone horizontally (left stick left/right for Mode 2).
• পিচ: Tilts the drone forward/backward (right stick up/down for Mode 2).
• রোল: Tilts the drone left/right (right stick left/right for Mode 2).

5.4 HDZero VTX Operation

The integrated HDZero VTX transmits video to your HDZero compatible goggles. Refer to your HDZero goggles manual for channel scanning and selection. The VTX settings (power, channel) can typically be adjusted via Betaflight OSD (On-Screen Display) menu using your transmitter sticks or through Betaflight Configurator.

6. রক্ষণাবেক্ষণ

নিয়মিত রক্ষণাবেক্ষণ আপনার ড্রোনের দীর্ঘায়ু এবং সর্বোত্তম কর্মক্ষমতা নিশ্চিত করে।

৭.৩.২ প্রোপেলার প্রতিস্থাপন

Damaged propellers can significantly affect flight performance and safety. Replace them immediately if bent, cracked, or chipped.

1. Use the provided propeller disassembly tool to carefully remove the old propeller from the motor shaft.
2. Ensure the new propeller is oriented correctly (clockwise or counter-clockwise rotation as indicated by markings or motor direction).
3. Gently push the new propeller onto the motor shaft until it sits flush. Do not force it.

6.2 পরিষ্কার করা

After flights, especially in dusty or grassy environments, clean your drone:

• Use a soft brush or compressed air to remove dust and debris from motors, flight controller, and camera.
• Avoid using liquids directly on electronic components.

6.3 Motor Care

Inspect motors for any signs of damage or excessive wear. Ensure they spin freely without obstruction. If a motor feels gritty or makes unusual noises, it may require replacement.

6.4 ফার্মওয়্যার আপডেট

Periodically check the Happymodel website or relevant community forums for updated Betaflight or ExpressLRS firmware. Updating firmware can introduce new features, improve performance, or fix bugs. Follow official update guides carefully.

7. সমস্যা সমাধান

This section addresses common issues you might encounter with your Mobula7 drone.

7.1 Drone Not Powering On

• ব্যাটারি পরীক্ষা করুন: ব্যাটারি সম্পূর্ণ চার্জ করা আছে এবং সঠিকভাবে সংযুক্ত আছে কিনা তা নিশ্চিত করুন।
• Inspect Connector: Verify the battery connector on the drone is not damaged or loose.
• চাক্ষুষ পরিদর্শন: Look for any visible damage to the flight controller or power distribution board.

7.2 No Video Signal (HDZero)

• Goggle Compatibility: Ensure your goggles are HDZero compatible and powered on.
• Channel Match: Verify that your goggles are tuned to the same channel as the drone's VTX.
• অ্যান্টেনা চেক: Ensure the VTX antenna on the drone and the antennas on your goggles are securely attached.
• VTX Power: Check VTX power settings in Betaflight OSD or Configurator.

7.3 Drone Not Arming

• Transmitter Link: Confirm your radio transmitter is powered on and successfully bound to the drone (solid receiver LED).
• Arming Switch: Ensure the arming switch on your transmitter is correctly configured and activated.
• Safety Pre-checks: Betaflight has safety checks. Connect to Betaflight Configurator and check the 'Setup' tab for any warnings (e.g., accelerometer calibration needed, low battery voltage, motor output issues).
• Throttle Position: Ensure your throttle stick is at its lowest position.

7.4 Unstable Flight / Drifting

• Propeller Damage: Inspect all propellers for damage and replace any that are bent, cracked, or chipped.
• মোটর সমস্যা: Check motors for debris, loose wires, or signs of damage. Ensure they spin smoothly.
• Accelerometer Calibration: In Betaflight Configurator, perform an accelerometer calibration on a level surface.
• পিআইডি টিউনিং: For advanced users, minor PID adjustments in Betaflight may be necessary, though the factory tune is generally suitable.
