Power HD Mini Servo HD-1711MG

via Pololu
SKU PL-2144

The HD-1711MG is a miniature-sized servo from Power HD with the same output spline as standard servos, making it compatible with standard-size servo horns. The gear train uses plastic gears near the motor to reduce weight and metal gears near the output shaft to allow it to deliver the kind of torque typically associated with larger servos. The output shaft is supported by a ball bearing for improved performance.

The 1711MG works with standard RC servo pulses, offering position control over a 145° operating angle for standard servo pulses between 800 µs to 2200 µs (the physically imposed limit angle is specified to be between 200° and 220°). The servo has a 7″ (18 cm) cable that is terminated with a standard JR-style connector, which is Futaba-compatible, and it includes additional servo horns and mounting hardware.

The servo cable is terminated with a Futaba-compatible JR-style connector.

Note that, as with most hobby servos, stalling or back-driving this servo can damage it.

Comparison to the FEETECH FT1117M mini servo

The FT1117M mini servo from FEETECH is a lower-cost alternative to the 1711MG with nearly identical dimensions and performance. The two servos should be generally interchangeable for most applications. The picture below shows both the FT1117M and the 1711MG side by side:
