Feature: 1. Lightweight Design: The 3.7g weight is very light, making the steering gear more flexible when running, suitable for applications requiring high mobility. 2. High Torsion Output: The servo has a high torsion output capacity, which can cope with large loads and ensure stable working performance. 3. Fast Response: the servo steering machine has a fast response speed and can quickly execute instructions, improving the response speed of the overall system. 4. Durable: The use of plastic materials and strict production process to ensure the durability of the servo steering machine, reducing maintenance costs. 5. Wide applicability: 3.7g servos are suitable for a variety of areas requiring precise control and fast response, such as drones, robots, remote control models, etc. Specification: Item Type: Servo Working Voltage: DC 3.7-6V Working Torsion: ≥0.45kgf·cm at 4.2V Working Speed: ≤0.1sec/60° at 4.2V Working Angle: 180°±10° (500~2500μs) Mechanical Limit Angle: 360° Size: Approx. 20 x 8.5 x 25mm / 0.8 x 0.3 x 0.1in Applicable: RC Cars, Fixed wing rc aircraft, Small Robots.
