SG90 9g Micro Servo 180 Degree for RC and Drone Builds

The SG90 is the standard reference micro servo in RC and hobby robotics, and this Readytosky unit is the same well-proven form factor: a 9 gram plastic-gear servo delivering 1.5 to 1.7kg/cm of torque across a 4.8V to 6V supply range, enough for control surfaces on small foam aircraft, pan-tilt camera mounts, and light robotic linkages without adding meaningful weight to the build.

Standard PWM control signal means it drops straight into any flight controller, receiver or Arduino servo library already written for hobby servos - no special driver or protocol to account for. At 0.12 seconds per 60 degrees of travel at 4.8V, response is fast enough for most control-surface and small gimbal uses, though it is a plastic-gear unit rather than metal-gear, so it suits light-duty applications rather than continuous high-load work.

Common uses include ailerons and rudders on small RC planes, pan-tilt camera and antenna tracker mounts, and general robotics projects needing a compact, inexpensive actuator.
