The Walkera QR X350 is a radio-controlled quadcopter designed for intermediate-level pilots, suitable for both indoor and outdoor environments. It is available in RTF (Ready-To-Fly) and BNF (Bind-N-Fly) completion levels.

Function Description:

The QR X350 is a sophisticated aircraft that integrates engineering materials, mechanics, electronics, aerodynamics, and high-frequency radio technology. Its primary function is flight, offering various control modes and advanced features to enhance the flying experience and safety. The aircraft is equipped with a main control board, GPS module, compass module, and a receiver, which work in conjunction with a compatible transmitter (DEVO-6/7/F7/8S/10/12S options) to provide precise control and autonomous functions.

The core flight control system includes:

GPS Hold System: This feature allows the aircraft to maintain a stable position using GPS coordinates, providing a hands-off hovering capability.
Stable Mode with GPS and Altitude Hold: This mode combines GPS positioning with an altitude sensor to keep the aircraft stable in both horizontal position and vertical height.
One Key Go Home: A safety feature that, when activated, commands the aircraft to return to its recorded starting position and land autonomously.
Failsafe to Return Home & Landing: In the event of signal loss or low battery voltage, the aircraft is programmed to automatically return to its home point and land, minimizing the risk of a crash.
Altitude Sensor: This sensor assists in maintaining a consistent altitude during flight.
Low Voltage Protection: When the battery voltage drops too low, the aircraft will provide a visual warning (slow blinking green LED) and initiate a slow descent to prevent a sudden crash.

The QR X350 is powered by brushless motors and ESCs (Electronic Speed Controllers), which are connected to a power board and an 11.1V 2200mAh LiPo battery. It can be equipped with an anti-vibration camera mount, suitable for a GoPro camera (camera excluded), allowing for aerial photography and videography.

Usage Features:

The QR X350 offers a range of features designed for ease of use and enhanced flight capabilities:

Control Modes: The aircraft supports three main control modes, selectable via a 3-position switch on the transmitter:
- Manual Mode: Provides direct control over the aircraft's movements. It is recommended to take off in manual mode.
- Position Hold Mode: Once activated, the aircraft will hover stably at its current position and altitude, allowing the pilot to use transmitter sticks for minor adjustments.
- One Key Go Home Mode: Initiates an autonomous return and landing sequence. The aircraft will return to its recorded starting position, land, and then lock its motors. To unlock, the pilot must switch back to manual mode.
Flight Time: The QR X350 offers a flight time of 10-15 minutes, depending on flight conditions and usage.
Camera Mount: An optional anti-vibration camera mount is available, designed to reduce shake and vibration for smoother aerial footage when using a GoPro camera.
FPV Version: An FPV (First Person View) version allows for live video transmission feedback directly to the radio, providing an immersive flying experience.
WiFi Version: An EXT function offers a low-cost WiFi version, enabling advanced functions and direct control via a mobile phone. The WiFi control range is stated to be above 250 meters.
Motor Unlock/Lock: Motors can be unlocked by moving the throttle stick to the lowest position and the rudder stick to the far left (in Manual Mode). To lock the motors, move the throttle stick to the lowest position and the rudder stick to the far right. Motors will not rotate when locked.
Compass Calibration: Essential for accurate GPS functionality, compass calibration should be performed before the first flight, when flying in a new environment, or when changing the original flight location. The process involves specific stick movements to enter calibration mode, followed by rotating the aircraft 360 degrees horizontally.
Gyro Calibration: The flight control system can perform gyro calibration automatically during code binding. Manual calibration is also possible by placing the aircraft horizontally, locking the motor, and performing specific stick movements.
Accelerometer Calibration: Similar to gyro calibration, accelerometer calibration can occur automatically during code binding or be performed manually using specific stick movements while the aircraft is horizontal and static.
GPS Satellites Signal Flowchart: The manual provides a flowchart indicating the number of GPS satellites acquired and the corresponding LED status (blinking frequency) to ensure the aircraft has a complete and accurate location fix before departure. A minimum of 5 satellites is required for GPS functions to work correctly.
Transmitter Control Settings: Detailed instructions are provided for configuring various parameters on DEVO-7, DEVO-6/F7/8S/10/12S transmitters, including model type, model selection, model name, swash type, device output, and reverse switch settings for different channels (Elevator, Aileron, Throttle, Rudder, Gear, Pitch, AUX2).
Aircraft Orientation: The manual defines the aircraft's orientation (front, back, left, right, up, down) to prevent confusion during operation and assembly.

Maintenance Features:

Proper maintenance is crucial for the safety and longevity of the QR X350.

Propellers Installation: Instructions are provided for correctly installing propellers, ensuring the spin-mark matches the motor's rotation direction.
Compass & Landing Gear Installation: Guidance on proper installation of the landing gear and compass module, including wiring and securing components.
Camera Mount Installation: Instructions for attaching the camera holding board and installing a GoPro camera (if applicable).
Brushless ESC/Motor/Power Board Connection: Detailed wiring diagrams and instructions for connecting the brushless ESCs to the motors and the power board, specifying clockwise and counterclockwise rotation for different motors.
Main Control Board Installation Requirements: Guidelines for installing the main control board, ensuring correct orientation (label side up, ESC connector towards forward), horizontal alignment, and clear access to all ports.
GA005 Balance Charger Instruction:
- Parameters: Specifications for the GA005 balance charger, including input voltage, input current, output current, dimensions, and weight.
- Features: The GA005 uses microcomputer chips for balanced charging of 2S or 3S Li-ion/Li-polymer battery packs. It automatically detects battery type and charges individual cells to 4.2 ± 0.05V, with a maximum voltage difference of less than 50 mV between cells.
- Operation Steps: Clear steps for connecting the wall adapter, inserting the battery pack, and monitoring the charging status via LED indicators (red solid for power on, flashing red for charging, solid green for saturated).
- Matters Needing Attention: Critical safety warnings for charger usage, including:
  - Charging in a dry, ventilated area away from heat and flammable substances.
  - Using only for 2S or 3S Li-ion/Li-polymer batteries; avoid charging multiple battery sets simultaneously.
  - Removing the battery from the helicopter during charging and never leaving it unsupervised.
  - Avoiding immediate charging after flight or when the battery is hot to prevent swelling or fire.
  - Ensuring correct polarity connections.
  - Preventing drops or violence to the battery to avoid internal short circuits.
  - Using original charging equipment and replacing swollen battery packs.
Battery Pack Maintenance:
- Storage: Store batteries in a dry, ventilated place at 18°C to 25°C.
- Charging/Discharging: Avoid frequent and excessive charging/discharging to prolong battery life.
- Long-Term Storage: Charge batteries to 50-60% saturation before long-term storage.
- Monthly Check: If stored for over a month, check cell voltage monthly; if below 3V, recharge to 50-60%.
- New Battery Motivation: New batteries should be charged and discharged 3-5 times (discharging no less than 70% saturation) to improve lifetime and voltage stability.
- Over-saturation: If left in the charger after saturation, the battery may self-discharge, and the charger will automatically re-charge it if cell voltage drops below rated voltage. Frequent re-charging shortens battery life.
Trimming Manual Flight Actions: Instructions for adjusting rudder, elevator, and aileron trims on the transmitter to correct any leftward, forward, or backward drift during takeoff.

The Walkera QR X350 emphasizes safety throughout its operation and maintenance, providing detailed guidelines to ensure a secure and enjoyable flying experience.
