SERVOMY SDS1901 SG90/MG90S Mini Size 180° HV Coreless Servo 5.0V-8.4V, Full Metal Case & Gears, 9.2 kgf·cm @ 8.4V, 0.07 sec/60°, Fits Standard 9g Servo Mounting for RC Car, Airplane, Helicopter, Robot

["9G-CLASS FOOTPRINT (19G ACTUAL WEIGHT): Designed as a high-performance drop-in replacement for standard SG90/MG90S servos. It shares the exact same mounting dimensions (24x12x22mm) for seamless installation in tight RC car chassis, micro crawlers, and drone airframes, while weighing 19g due to its heavy-duty full-metal construction.","HIGH VOLTAGE 2S LIPO DIRECT DRIVE: Engineered with a premium coreless motor that supports a wide DC 5.0V-8.4V range. At 8.4V, it delivers a robust 9.2 kgf.cm stall torque and an ultra-fast 0.07s/60° transit speed, providing immediate and authoritative steering response for RC vehicles without the need for external BECs.","BONUS ALUMINUM SERVO HORN INCLUDED: To maximize the mechanical advantage of the 9.2kg.cm torque, this package includes a premium CNC-machined aluminum servo horn alongside the standard plastic set. This eliminates steering linkage flex under heavy loads—saving you the extra cost and hassle of buying aftermarket metal upgrades.","FULL METAL THERMAL EFFICIENCY & DURABILITY: Features a CNC-machined full-metal housing that acts as a structural heatsink, effectively dissipating heat during continuous steering or trailing sessions. The internal drivetrain utilizes a 390:1 reduction ratio with all-metal gears, offering exceptional resistance to gear stripping during hard bashes or heavy payload drops.","DIGITAL PRECISION & STALL PROTECTION: Operates via a digital amplifier at a 333Hz high-frequency refresh rate, supported by a single ball bearing (1BB) and a 21T (4.9mm) metal spline for near-zero radial play. The built-in MCU includes an intelligent stall protection algorithm, actively safeguarding the PCB and motor from burning out if your RC crawler's wheels bind against rocks."]
