Suitable For Airplane Robotics: In hobbyist and educational robotics, 35kg servos are used to move heavy arms, legs, or other components of robots. Their strength is essential for creating robots that can lift or manipulate objects. Suitable For Mini Helicopter RC Vehicles: include RC cars, trucks, boats, and planes. high torque is beneficial for steering mechanisms and controlling large-scale models. Review: How to use with Arduino Servo Library - Continuous operation servos like these are different from regular servos but still work well with the Arduino Servo library. The position is not accessible with 360 degree servos. Instead you use the Servo library to set the speed and direction of the motor. Because these are geared motors, you get more torque than you would with a regular DC motor. The 5 servos I received responded perfectly to the Arduino Servo library as described here: servo.write(0); // fast CW servo.write(180); // fast CCW servo.write(90); // stop // 0 to 90 (fast to slow) CW, front view) // 90 to 180 (slow to fast) CCW, front view) // 90 = stop If you look at the pulse widths generated for each of these settings and the operation of 360 degree servos, this is all as it should be. You should never have to cut the power to stop the servo. Review: Worked as they should - Worked as they were supposed to. ## Features - MINI REMOTE CONTROL SERVO : 5 packs FS90R RC servo is composed of PC plastic shell, POM gear, iron core shaft, light weight and small size. - HIGH ROTATION SPEED SERVO: the servo rotation angle is 360 degrees (at 1200→1800μsec), and the dead zone width is ≤90 μsec, compatible with Arduino and Raspberry Pi - LARGE COMPATIBLE MOTOR: This servo system is pulse-controlled, compatible with 1/8 and 1/10 scale remote control robots, trucks, off-road vehicles, robotic arms, and any application that uses standard servo systems - STRONG STALL TORGUE MOTOR: (4.8V) 18.09oz/in(1.3kg/cm), (6V) 20.86oz/in(1.5kg/cm) The working voltage is 4.8V-6V.
