If you're into robotics, RC cars, drones, or any DIY project that needs serious muscle, this high-power servo is a beast! It operates on DC 12-24V and delivers an impressive maximum torque of 180kg.cm at 24V (90kg.cm at 12V) - and that's actual measured torque, not just theoretical. The arm plate is made from tough, hard alloy steel with anti-oxidation treatment, so it's durable and resistant to wear. It's compatible with many remote systems like Futaba, JR, SANWA, Hitec, and others. It accepts multiple input modes: pulse signal (0.5-2.5ms range for remotes, multi-servo controllers, microcontrollers) or analog voltage signal (potentiometer). The rotation angle is a wide 300 degrees with precise control (0.32-degree accuracy). Installation is easy thanks to the D-hole anti-slip key connection that fits ASMC/ASME servo axes. Even if a fuse blows, it's designed to keep working safely. Perfect for heavy-duty applications where reliability and power are key!
