Five stages of quality control

1. Design phase: Build prototype machines for testing and optimize the design based on feedback.

2. Procurement phase: Evaluate suppliers to ensure the quality of materials and components. Incoming inspection: Conduct strict quality inspections on raw materials and parts.

3. Production phase: Develop a reasonable process flow and operating standards, and arrange inspectors to monitor production quality.

4. Testing phase: Assess the main performance indicators of drones, such as payload, speed, endurance, etc. Reliability testing: Simulate complex working conditions and environments to verify the reliability of drones.

5. Actual flight testing phase: Fully test drones in real environments to ensure quality and performance.
