By the end of this lesson, you will be able to:

1. Explain why testing and balance are critical for stable flight.
   → Answer: Drones rely on perfect balance; uneven rotation or weight causes shaking or tilting.

2. Identify and fix common flight issues like drift or uneven lift.
   → Answer: You’ll learn to observe propeller and motor performance to find the cause.

Apply the idea of iteration — testing, analyzing, and improving.
→ Answer: Each test gives feedback that helps you make small but powerful improvements.
