Power HD High-Torque Servo 17KG Analog Servo HD-1501MG

The Power HD HD-1501MG Analog Servo is a professional-grade, standard-size servo motor designed to deliver exceptional torque, speed, and reliability for demanding RC, robotics, and automation applications. Engineered with all-metal gears (MG) and dual ball bearings, the HD-1501MG offers excellent durability and smooth operation even under heavy mechanical loads, making it a popular choice among RC enthusiasts, robotics builders, and engineering students.

With a stall torque of 17 kg·cm at 6V (15.5 kg·cm at 4.8V) and a fast operating speed of 0.14 sec/60° at 6V, this servo combines high power and quick response — a combination that's hard to find in standard-sized servos. Its rugged metal gear train is far more wear-resistant than nylon-geared alternatives, providing a much longer service life, especially in applications involving shock loads, sustained high-torque operation, or rough handling.

The HD-1501MG accepts standard RC servo pulses (typically 1ms to 2ms at 50Hz) and provides a wide operating angle of approximately 165° over a servo pulse range of 800 µs to 2200 µs. This makes it directly compatible with the Arduino Servo library, PCA9685 servo controllers, RC receivers, and any standard PWM-capable microcontroller including ESP32, STM32, and Raspberry Pi.

The servo is supplied with a generous 10-inch (25 cm) lead terminated in a standard 3-pin JR-style connector that is fully Futaba-compatible, making it easy to plug into RC receivers, servo controllers, or Arduino prototyping setups. Standard mounting hardware (screws, horns) is included for easy installation in any project.

Whether you're building a large robotic arm, an RC truck, a steering mechanism, a pan-tilt camera mount, or an animatronic prop, the HD-1501MG provides the muscle, precision, and durability required for serious projects — at a price that's friendly for hobbyists.
