4.2 Load Fixing-Plate Installation

To enable payload dropping functionality, install the Load Material Fixing-Plate and Hook Servo onto the drone's frame. Refer to the following steps and the accompanying video for detailed instructions:

1. Connect the servo cable from the Load Fixing-Plate Hook Servo to the designated port on the drone's flight controller.
2. Carefully wrap the servo cable under the plate to ensure it does not interfere with drone operation.
3. Align the Load Fixing-Plate with the mounting points on the drone's underside.
4. Secure the plate using the provided screws (7 screws for the hook) and the 2.0mm Hex Wrench. Ensure all screws are tightened securely.

4.3 Battery Charging

Use the included HOTA D6 Pro Charger to charge the 6S battery. This smart charger supports AC/DC dual-channel charging with a maximum power of 650W and 15A charging current, ensuring efficient and safe charging.

5.1 Pre-Flight Checklist

• Ensure the drone battery is fully charged and securely installed.
• Verify the AT9S Pro transmitter battery level is sufficient.
• Check all propellers for damage and ensure they are tightly secured.
• Confirm the flight area is clear of obstacles and people.
• Power on the transmitter first, then the drone.

5.2 Autonomous Flight and Waypoint Planning

The M435, with its integrated flight controller and GPS TS100, supports pre-set flight routes for autonomous operations. This allows for tasks such as autonomous takeoff, landing, and automatic package delivery by following defined waypoints.
