4pcs MG90D 9g Digital Micro RC Servo, Full Metal Gear Mini Servo Motor Upgrade SG90 Compatible with Arduino RC Smart Car Robot Arm 450 Aircraft Boat

[MG90D Micro Servo] - MG90D digital micro servo motor, an upgrade from the MG90S SG90 9g servo motor. [Aluminum Metal Gear Servo] - The internal structure is made of high-quality all-metal material, improving performance. It is quieter, smoother, and more precise. Copper bearings provide greater stability and less wear. [Wide Range of Applications] - The MG90D digital micro servo is ideal for those looking for a high-quality, versatile, and affordable servo motor. It can be widely used in RC airplanes, helicopters, fixed-wing aircraft, quadcopters, RC cars, boats, automobiles, gliders, electronic DIY projects, small robots, robot kits, and more. [Torque and Speed] - Operating Voltage: 4.8V-6.0V, Peak Stall Torque: 2.2kg/cm (6V). No-Load Speed: 0.12 sec/60° (4.8V) / 0.09 sec/60° (6V); [PWM Control System] - The control system is PWM (Pulse Width Modulation). Pulse width range: 500-2500 μsec. Operating angle: 270°±3° for 500-2500 μsec.
