Q1. Why is balance important in drone flight?
Answer: Without balance, the drone vibrates, tilts, or crashes because propellers and motors produce uneven thrust.

Q2. What should you do if one motor spins slower than the others?
Answer: Check the motor’s connection, ESC wiring, or replace the motor if needed to ensure equal power.

Q3. What does iteration mean in engineering?
Answer: It means improving a design by testing, fixing, and trying again multiple times.

Q4. What are the three main reasons a drone might wobble?
Answer:

1. Uneven propeller weight

2. Weak or damaged motor

3. Wrong calibration or sensor issue
   

Q5. How can you fix a propeller imbalance?
Answer: Add a small tape piece to the lighter side until rotation is smooth and stable.
