5. Налада і падключэнне

5.1. Mounting the Flight Controller

• Mount the A3 Pro/A3 Pro V2 firmly to the airframe using the provided double-sided tape.
• Ensure the controller is mounted horizontally and parallel to the main axis of the aircraft.
• The arrow on the controller should point towards the nose of the aircraft.
• Avoid mounting near sources of vibration or electromagnetic interference.

5.2. Standard Receiver Connection (A3 Pro)

For standard PWM receivers, connect the receiver outputs to the corresponding inputs on the A3 Pro.

5.3. Serial Receiver Connection (A3 Pro V2)

The A3 Pro V2 supports various serial receiver protocols, simplifying wiring. Connect your serial receiver to the "Serial RX/G" port.

When operating in PPM or Serial Receiver Mode, the "THR Out/AIL" port provides the throttle channel output for the ESC or throttle servo.

6. Рэжымы працы

Both A3 Pro and A3 Pro V2 offer 6 distinct flight modes to suit various flying styles and conditions. These modes are typically selected via a switch on your transmitter connected to the Flight Mode Control Channel (MOD).

• Gyro-Off Mode (GYRO OFF): The flight controller's stabilization functions are completely disabled. The aircraft responds directly to pilot inputs.
• Нармальны рэжым (NORMAL): Provides basic stabilization, assisting in maintaining level flight and counteracting external disturbances like wind.
• Trainer Mode: (A3 Pro specific) Offers enhanced stability and limits control surface throws, ideal for beginners.
• Atti-Lock Mode (LOCK): (A3 Pro V2 specific) Locks the aircraft's attitude (pitch and roll) at the last commanded position, providing a very stable platform.
• Auto-Level Mode (ANGLE/LEVEL): Automatically levels the aircraft when control sticks are released, preventing extreme attitudes.
• Auto-Hover Mode (HOVER): (A3 Pro specific) Attempts to maintain a stable hover, useful for specific maneuvers or VTOL aircraft.

Refer to the full user manual for detailed calibration and configuration of each mode.

7. Тэхнічнае абслугоўванне

• Фізічны агляд: Regularly check the flight controller and its connections for any signs of damage, loose wires, or wear.
• Mounting Security: Ensure the double-sided tape is still securely holding the unit and that there is no excessive vibration.
• Абнаўленне прашыўкі: Check the HobbyEagle website periodically for firmware updates for your specific model (A3 Pro V2 is upgradable with an optional data cable). Follow update instructions carefully.
• Ахова навакольнага асяроддзя: Keep the flight controller away from moisture, extreme temperatures, and direct sunlight.

8. Выпраўленне непаладак

• No Response from Controls:
  • Check all wiring connections between the receiver, flight controller, and servos.
  • Ensure the receiver is powered and bound to the transmitter.
  • Verify correct channel assignments in your transmitter and flight controller settings.
• Unstable Flight / Erratic Behavior:
  • Confirm the flight controller is mounted securely and correctly oriented (arrow pointing forward).
  • Check for excessive vibrations in the airframe.
  • Adjust gain settings. Start with lower gains and gradually increase until desired stability is achieved without oscillation.
  • Recalibrate the gyros if necessary.
• Incorrect Flight Mode Operation:
  • Ensure the flight mode control channel (MOD) is correctly assigned and calibrated on your transmitter.
  • Verify the switch positions correspond to the desired flight modes.
• Праблемы са святлодыёдным індыкатарам:
  • Refer to the full user manual for specific LED status indications and their meanings.
  • A blinking LED often indicates a calibration requirement or an error state.

9. Карыстальніцкія парады

• Start with Low Gains: When first setting up, always begin with conservative (low) gain settings and gradually increase them during test flights to avoid over-correction and oscillations.
• Бяспечная правадка: Use cable ties or electrical tape to secure all wiring, preventing them from interfering with moving parts or causing disconnections due to vibration.
• Test Flight Environment: Perform initial test flights in a calm, open area with plenty of space, especially when experimenting with new settings or modes.
• Read the Full Manual: For advanced configurations, detailed calibration procedures, and specific troubleshooting steps, always consult the comprehensive PDF user manual.
