The GOTECK 5g digital micro servo set is engineered for high-precision performance in micro-scale RC applications. It has a full metal gear system with hard anodising, which the listing says gives exceptional durability, prevents tooth wear and extends the operating lifespan.
The key features listed are full metal gear construction, high-precision performance, extra-large torque output, fast and accurate response, intelligent overload protection, a wide control range, versatile application use and a compact, lightweight body.
The specification table gives a torque of 1.2kg.cm at 4.8V and 1.4kg.cm at 6V and a no-load speed of 0.11s/60 degrees at 4.8V and 0.06s/60 degrees at 6V.
Full metal gear construction: hard-anodised gears resist tooth wear.
High-precision performance: accurate positioning.
Extra-large torque: 1.2kg.cm at 4.8V and 1.4kg.cm at 6V.
Fast, accurate response: 0.06s/60 degrees at 6V.
Intelligent overload protection: protects the servo under load.
Wide control range: 180 degree corner angle.
Compact and lightweight: 21.3 x 11.5 x 20.6mm.
A hobby servo combines a small motor, a gearbox and a position sensor with control electronics. You send it a pulse every 20 milliseconds or so, and the width of the pulse tells it where to go: about 1.5 milliseconds is centre, with roughly 1.0 and 2.0 milliseconds at the ends. The servo drives its output shaft until the sensor says it has reached the commanded position, then holds it against the load.
Digital servos process the signal with a microcontroller and drive the motor at a much higher rate than analogue servos, which gives faster response, a smaller dead band and stronger holding torque. Metal gears cope better with shock loads than plastic ones, and ball bearings keep the shaft smooth and reduce wear.
Always power a servo from a supply that can deliver its peak current, not from a weak receiver port, and keep the linkage free so the servo never strains against a mechanical stop. A stalled servo draws a large current and can overheat within seconds.

Replacing a worn plastic-gear micro servo
The specification table lists a DC motor, metal gears, a plastic case, an operating temperature of -20 to +60 degrees C, a working voltage of 4.8 to 6V DC, a 1520us / 333Hz working frequency, a 200mm 28AWG lead and a 180-degree corner angle. The product weight is listed as 7.8g, although the product title refers to a 5g servo.
Wire colours are black for negative, red for positive and white for the signal. The package includes the servo and a servo accessory kit.
