How does a chipped or damaged propeller affect performance?
- A.It improves thrust by reducing weight
- B.It has no measurable effect on a multirotor
- C.It reduces efficiency and adds vibration, shortening endurance and straining motors
Correct answer
C. It reduces efficiency and adds vibration, shortening endurance and straining motors
Why
Propellers convert motor power into thrust, and damage disrupts that conversion. The result is wasted energy, vibration, and extra motor load for the same lift.
