💡 What is a high-torque digital servo used for in RC models and robotics?

It's handy for steering, gripping, and moving heavy parts where strong, precise control matters. - Ideal for steering and actuation on 1/8 and 1/10 scale RC cars - Great for robotic arms, grippers, and pan-tilt camera mounts needing repeatable 270° moves - Uses standard PWM pulse widths (500usec-2500usec) for easy controller compatibility - Durable metal gears and dual bearings minimize wear, noise, and heat in tough sessions
