What it is
The ShillehTek SG92R Micro Servo Motor 9g Carbon Fiber Gears 2.5kg for RC Plane is a compact digital micro servo in the familiar 9g form factor, designed for precise 0–180° positioning in small RC planes, hobby robotics, and Arduino automation. Carbon fiber gears improve durability over basic nylon gears, while digital control helps deliver snappier response and tighter deadband for control surfaces and lightweight mechanisms.
Pins
This is a standard RC-style micro servo with a 3-wire lead (signal, power, ground). For exact wire color order and connector orientation, refer to the listing photos and the servo plug as used on your receiver/servo tester/Arduino servo header.

Frequently Asked Questions
Is the SG92R compatible with SG90 mounts and horns?
Yes. This servo is in the familiar 9g form factor and is described as fitting SG90 mounts, making it a straightforward swap for many small RC and maker builds.
How do I connect the SG92R micro servo to an Arduino?
Use a standard servo connection: signal to an Arduino PWM-capable pin, plus power and ground. For reliability under load, power the servo from a suitable external supply and share ground with the Arduino.
Does the SG92R support 0–180 degree control?
Yes, the product description specifies a full 0–180° range, which works well for control surfaces and small mechanisms.
What is the torque of the ShillehTek SG92R 9g servo?
It is described as delivering a practical 2.5 kg·cm stall torque (2.5kg/cm), suitable for small airplanes, hobby robotics, and light automation tasks.
What is the benefit of carbon fiber gears in a micro servo?
Carbon fiber gears are reinforced for improved durability and can better resist stripping compared with standard nylon gear servos, especially in higher-load or crash-prone RC applications.
