Product Overview
SG92R Micro Digital Servo (Carbon Fiber Gears, 2.5kg Torque)
The SG92R is a high-performance digital upgrade to the classic SG90 micro servo. Weighing only 9g, it offers significantly more power and durability by utilizing carbon fiber reinforced POM gears. It is an ideal choice for weight-sensitive applications requiring precision and reliability, such as 3D park flyers, high-speed jets, 250-450 size RC helicopters, and educational robotics.
Key Features
- Enhanced Durability: Features a gear set made of POM (Polyoxymethylene) with Carbon Fiber, which is more wear-resistant than standard nylon gears.
- High Torque Output: Delivers a powerful 2.5kg/cm stall torque at 4.8V, providing excellent holding power for its small size.
- Fast & Precise Response: The digital control system ensures constant torque throughout the travel range and a quick reaction speed of 0.1 seconds per 60°.
- Lightweight Design: Compact dimensions and a weight of just 9g minimize the impact on your aircraft's center of gravity.
- Universal Compatibility: Equipped with a standard JR/Futaba universal connector and a 25cm cable, making it compatible with almost all RC receivers and microcontrollers like Arduino.
