Our Review
After integrating the SUNGOOYUE 20KG Digital Servo, High RC Servo Motor Waterproof Full Metal Gear, with 25T Horn, for 1/8 1/10 /12 RC Car Robot Crawler Truck (30kg) into several test builds, we found it to be a capable component for the price. Key specs include Torque: 15 kg-cm, Operating Voltage: 6V - 7.4V, Speed: 0.14 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 SUNGOOYUE 20KG Digital Servo, High RC Servo Motor Waterproof Full Metal Gear, with 25T Horn, for 1/8 1/10 /12 RC Car Robot Crawler Truck (30kg) 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
