Power HD Mini Servo HD-1711MG
The HD-1711MG from Power HD is a miniature-sized servo with the same output spline as standard servos, making it compatible with standard-sized servo horns. The gear train is a mixture of metal and plastic gears to keep the servo light but strong, and the output shaft is supported by a ball bearing. Servo horns and associated hardware are included.
Key specs at 6 V: 0.11 sec/60°, 50 oz-in (3.5 kg-cm), 18.5 g.
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.
