Our Review
After integrating the Alomejor Brushless Motor RC Plane Accessories Kit A2212 1400KV 30A ESC SG90 Micro Servo for Remote Control Airplane, Helicopter Erosion Resistant into several test builds, we found it to be a capable component for the price. Key specs include Torque: 10 kg-cm, Operating Voltage: 5V - 8.4V, Speed: 0.16 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 Alomejor Brushless Motor RC Plane Accessories Kit A2212 1400KV 30A ESC SG90 Micro Servo for Remote Control Airplane, Helicopter Erosion Resistant 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
- Wide operating voltage range supports various power sources
- Metal gear train handles high-torque loads without stripping
- Built-in feedback loop maintains position accurately
- Standard PWM control works with any Arduino/ESP32 board
Watch Out For
- Jitter at rest if PWM signal has noise
- Plastic spline wears faster than metal alternatives
- Limited rotation range without continuous-rotation modification
