Our Review
After integrating the 10PCS SG90 9G Mini Servo Servo Motor for RC Planes Robot Arm Fixed-Wing Servo Motor Control for Airplane 360° into several test builds, we found it to be a capable component for the price. Key specs include Torque: 10 kg-cm, Operating Voltage: 6V - 7.4V, Speed: 0.20 sec/60°.
Mechanical performance was consistent in our testing. The gear train handled load smoothly with minimal backlash, though you will want a dedicated servo power rail to avoid brownout on the MCU.
Wiring was straightforward. Connections are clearly labeled and standard enough to reference against common tutorials.
Overall, the 10PCS SG90 9G Mini Servo Servo Motor for RC Planes Robot Arm Fixed-Wing Servo Motor Control for Airplane 360° fills its role well. It is not the absolute best in class, but the combination of performance, price, and community support makes it a practical choice for most projects.
What We Like
- Standard servo horn and mounting hardware included
- Quick response time for real-time control applications
- Spline output shaft accepts universal servo accessories
- Metal gear train handles high-torque loads without stripping
Watch Out For
- Draws high peak current that can brownout weak power supplies
- Plastic spline wears faster than metal alternatives
- Jitter at rest if PWM signal has noise
