The EMAX 8.5g ES08D II digital servo is a compact, lightweight small servo for precision control in RC helicopters, airplanes and robotics projects. It is built from durable materials with a robust gear set for smooth, responsive and accurate movement.
A sturdy case improves reliability in operation, and the included servo horns and mounting screws make installation quick. The listing says it suits hobbyists and professionals who want dependable performance in a compact size.
The specification table gives an operating voltage of 4.8 to 6V, a stall torque of 1.6 kgf.cm at 4.8V and 2.0 kgf.cm at 6V, speeds of 0.12 and 0.10 seconds per 60 degrees, and a weight of 8.6g.
High-quality material and gears: a robust gear set.
Smooth, precise control: responsive movement.
Easy to install: servo horns and mounting screws included.
For RC aircraft, micro robots and DIY: a versatile small servo.
Digital servo: fast response with plastic gears.
Light: 8.6g.
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.
