The Hitec HS422 servo has been a long - standing favorite, thanks to its durability and easy - modification feature. It's an ideal choice for low - cost robotic applications. With bronze bushings supporting the output shaft at the top and bottom and an indirectly - driven potentiometer, it can be effortlessly adapted for wheeled applications. The separate circuit board from the motor allows easy access to the potentiometer. This servo offers outstanding performance at an affordable price. Specifications include a +Pulse Width Control system with 1500usec Neutral, a 3 - 5 Volt Peak to Peak Square Wave required pulse, an operating voltage range of 4.8 - 6.0 Volts, and an operating temperature from -20 to +60 Degree C. It has different operating speeds and stall torques at 4.8V and 6.0V, a 45 - degree operating angle, and is 360 - degree modifiable. The current drain, dead - band width, motor type, potentiometer drive, bearing type, gear type, connector wire length, dimensions, and weight are all clearly specified. The shipping list includes one Hitec HS422 Servo.
Using the Hitec HS422 servo is quite straightforward. First, make sure to connect it to a power source within the 4.8 - 6.0V range. The required pulse is a 3 - 5 Volt Peak to Peak Square Wave. When you want to use it for robotic applications, you can take advantage of its easy - modification feature to adapt it for wheeled use. For the best performance, keep it within the operating temperature range of -20 to +60 Degree C. As for maintenance, since it has nylon gears, avoid over - stressing them. Regularly check the bronze bushings for any signs of wear. If you need to access the potentiometer, it's easy because the circuit board is separate from the motor. Just be careful when handling the servo to prevent any damage to the internal components.
