Servo speed measures how quickly a servo can move to a new position, affecting the responsiveness of your RC model. Choosing the right speed is crucial for applications requiring precision and quick reactions, such as in racing or aerobatic models.
Popular options
0.14 - 0.2 s
Typical price
31.– to 85.–Provides slower response times, suitable for applications where high speed is not essential.
Recommended for beginners or models where precision is more important than speed.
