Features Compact and Space Saving: Reasonable size and light weight, portable to carry and use. High quality and fine workmanship, rust-proof, durable and practical. Smooth edge design, good performance, stable and durable. Easy to install, for modeling airplanes/cars/robots. The steering gear with a mean value adjustment potentiometer (open shell to pry the board to see), the debugging can be adjusted to 1.5 ms to observe the standstill of the steering gear when you stop and turn on the control potentiometer until the stall s The signal port must be input with a 50Hz rectangular wave, then the duration of the high level pulse used to control the signal cycle can control the speed and forward/reverse rotation as well as stalling. The duration of the high level corresponds to one speed. When the high level is 1ms - 1.5ms, the servo will rotate forward (the rotation speed is fastest when it is 1ms, the higher the lower, the servo will stop turning when 1.5ms is reached). When the high level is 1.5-2ms, the servo rotates backwards (the servo stops turning when 1.5ms is reached, when the duration is closer to 2ms, the closer the faster. The reverse rotation speed is fastest when 2 ms are reached) Specification: Condition: 100% Brand New Item type: 360 degree continuous rotation servo motor Material: metal and plastic. Colour: black. Product size: approx. 40.8 x 20 x 39.5 mm / 1.6 x 0.8 x 1.6 inches. Weight: approx. 52 g / 1.8 ounces. Torques: 5.5 kg/cm (at 4.8 V).
