How will controllability be affected by being overweight?

• A. Lower
• B. Higher
• C. Unchanged
• D. More difficult

Answer: (B)

Controllability is about how quickly and precisely you can change the drone’s motion in response to control inputs. When a drone carries extra weight, its inertia increases, so it resists changes in speed and direction more. The motors must produce more thrust to achieve the same acceleration and attitude changes, which reduces the thrust-to-weight ratio. That means the aircraft responds more slowly to stick inputs, making quick, precise maneuvers harder. So overweight tends to make controllability more difficult, even if the extra mass can add some passive stability in gusty conditions.
