This standard steering servo features a stable and fast response time, powerful linearity, precision thanks to its high-precision potentiometer, stable low noise, and waterproofing. It's ideal for RC cars and boats. It's suitable for all 1:8 to 1:12 scale RC trucks. It features a high-precision metal gear with a hard-anodized CNC aluminum middle shell. It's a high-torque steering servo for robot arms, boats, vehicles, and remote-controlled toys. It offers a high rotation speed of 270 degrees, with well-controlled rotation. It also offers 360 degrees of rotation when powered off, making it ideal for robot joint movements. The servo's pulse width signal ranges from 500 to 2500 microseconds. An input signal of 500 microseconds results in a 0-degree angle, and a signal of 2500 microseconds results in a 270-degree angle. Includes 4 x 270-degree DS3218 digital servos, 4 x 25T servo horns, and 4 x accessories.
