Beffkkip MG90S Micro Servo Motor 4-Pack – Metal Gear, 9g, for Arduino and RC Projects
Beffkkip MG90S Micro Servo Motor 4-Pack – Metal Gear, 9g, for Arduino and RC Projects
The Beffkkip MG90S micro servo motor is a metal-gear upgrade to the common SG90, providing higher durability and reduced noise for RC projects. Each pack includes four servos, each with a stall torque of 2.0 kg/cm at 4.8V and an operating speed of 0.11 seconds per 60 degrees. With aluminum metal teeth, a coreless motor, and double ball bearings, these mini servos are built for reliable performance in robots, cars, planes, and Arduino builds.
What torque and speed can you expect from the MG90S?
At 4.8V, each servo delivers 2.0 kg/cm of stall torque and rotates 60 degrees in 0.11 seconds. This makes them suitable for a wide range of RC and robotic applications where precise, quick movement is needed. The metal gears help maintain accuracy under load.

What materials make up the MG90S servo?
These servos feature aluminum metal teeth for the gears, which are more durable than the plastic gears found in standard SG90 servos. The coreless motor design reduces weight and improves response time. Double ball bearings support the output shaft, reducing friction and noise during operation.
How does the MG90S compare to the standard SG90?
The MG90S is described as an updated version of the SG90. Key improvements include metal gears instead of plastic, a coreless motor, and double ball bearings. These changes contribute to greater durability, less noise, and smoother operation, making the MG90S a better choice for projects that demand consistent performance.
Common Questions About This Micro Servo
What voltage should I use?
The specified torque and speed are measured at 4.8V. The data does not indicate other operating voltages, so for best results, use a stable 4.8V supply.
How many servos are included?
This listing includes four MG90S servos. Each is a 9g class micro servo, ideal for projects that require multiple actuators.
Is this servo compatible with Arduino?
Yes, the title indicates it is designed for Arduino projects. Many standard servo libraries work with these motors out of the box.
What is the noise level like?
The metal gears and double ball bearings help reduce operational noise compared to plastic-gear servos. The product description notes “less noise” as a benefit.
With over 595 ratings and a 4.3 out of 5-star average, the Beffkkip MG90S servo pack has been well received by hobbyists and makers alike. It ranks #13 in RC Servos on Amazon, reflecting its popularity in the category.
