The main difference between these servo engines lies in the differences in gear material, torque, and rotation angle.

The SG90 is widely used for basic purposes. Except for different rotation angles, the SG90 90 90 degree, 180 degree, and 360 degree plates are all the same. The MG90S is equivalent to the metal tooth plate reinforcement of the SG90, and the installation dimensions are slightly different from those of the SG90. The external dimensions, torque, and other parameters of the steering gear at 90 degrees and 180 degrees are consistent, but the ultimate rotation angle is different. A 360 degree steering gear rotates continuously.

The fixed wing S-version servo (with a line length of 25CM) is not a helicopter version. Compared to the helicopter version, it has lower tension, performance, and motor life, making it suitable for electric fixed KT boards or bubble engines (recommended) with high cost-effectiveness.

360 degree servo: It is actually equivalent to a continuously variable speed reduction motor, which can control speed and direction. There is no function for 0-360 degree angle control. The control method is the same as the control signal of a general servo.
