Digital standard servo with metal gears for model aircraft. Max. torque: 9 kg at 7.4 V. Max. speed: 0.13 s at 7.4 V. Operating voltage: 6 - 7.4 V. Weight: 47 g. Dimensions: Length: 40 mm, Width: 20 mm, Height: 38.1 mm. Digital servo for precise control commands. Digital servos have a higher angular resolution compared to analog servos, and the servo position is regulated faster and more accurately. Furthermore, they are often programmable, allowing for adjustments to the zero point and speed, for example. Additionally, a digital servo requires about four times more power than an analog servo.
