Here are some key features and characteristics of the ES3302 servo:

Metal Gear Train: The servo features a metal gear train, which enhances its durability and allows it to handle higher loads and stress compared to servos with plastic gears. Metal gears are essential for applications where strength and longevity are important.

Analog Servo: The ES3302 is an analog servo, meaning it operates using traditional analog control signals, typically in the form of PWM (Pulse-Width Modulation) signals, to adjust its position. Analog servos are commonly used in various RC applications, especially when precise positioning is not the primary concern.

12.4-Gram Weight: The 12.4-gram weight classifies this servo as mini-sized. It's relatively compact and lightweight, making it suitable for a variety of RC glider models.

Application: The ES3302 servo is designed for use in RC gliders, particularly for controlling various components such as ailerons, elevators, and other control surfaces.

Voltage and Current Requirements: Check the voltage and current requirements of the servo to ensure compatibility with your power source, such as a receiver or servo controller.
