Hitec HS-311

Type: Standard Servo

Torque: Approximately 3.7 kg/cm at 6V

Advantages: Known for reliability and good performance, the Hitec HS-311 is a popular choice among hobbyists. Although it is typically more expensive than the SG90, its increased torque and reliability make it a worthwhile investment for demanding applications.

Savx SC-0251

Type: High Torque Servo

Torque: Approximately 6 kg/cm at 6V

Advantages: The Savx SC-0251 is excellent for applications requiring high precision and torque. With a reputation for quality and reliability, this servo motor is a top choice for projects that demand exceptional performance.

Futaba S3003

Type: Standard Servo

Torque: Approximately 3.2 kg/cm at 6V

Advantages: The Futaba S3003 is a reliable and widely used servo motor in various applications. Although it is pricier than the SG90, its durability and performance make it a wise investment for those who need a dependable motor.

Considerations When Choosing a Servo

Torque Requirements: Determine how much torque you need for your specific application. Size and Weight: Ensure the servo fits within your project dimensions. Speed: Consider how fast the servo needs to respond. Durability: Metal gears offer better longevity compared to plastic gears. Budget: Higher performance servos can be significantly more expensive.

Conclusion

For most hobbyist applications, the MG90S is a good upgrade if you need a drop-in replacement. However, if you're working on high-torque projects, the DS3218 or Savx SC-0251 could be more suitable. Always assess your specific application requirements when selecting a servo motor to ensure the best fit for your project.

Note: The AGFRC Micro Servo 9g Servo Motor - Digital 11g Metal Gear Mini Servo Control Angle 180deg; has a 2.2 Kg/cm stall torque, making it a robust and durable alternative to the TowerPro SG90.
