SERVOMY SDS2451 24g Micro Brushless Servo, 5.0V-8.4V HV Digital, Full Metal Case & Steel Gears, 9.5 kgf·cm / 0.06 sec @ 8.4V,Aluminum Horn Included, for 450 Helicopter, eVTOL, Fixed-Wing UAV

["BRUSHLESS MOTOR EFFICIENCY & LONGEVITY: Upgraded with a high-performance brushless motor, offering significantly higher power density and lower heat generation compared to traditional coreless or brushed motors. This frictionless design dramatically extends the operational lifespan, making it highly reliable for continuous, high-stress UAV flight operations.","HEAVY-DUTY STEEL GEAR DRIVETRAIN: The internal 299:1 reduction system exclusively utilizes high-strength steel gears, providing vastly superior durability and wear resistance over standard aluminum or brass/copper gears. Paired with dual ball bearings (2BB), it ensures precise power delivery and prevents gear stripping under heavy aerodynamic loads or harsh landings.","ALUMINUM SERVO HORN INCLUDED: To maximize the mechanical advantage of the 9.5 kgf·cm torque, this package includes a premium CNC-machined aluminum servo horn (25T 4.9mm spline) alongside the standard plastic set. This eliminates steering and linkage flex under high-torque demand—saving you the extra cost of buying aftermarket metal upgrades.","HIGH VOLTAGE 2S LIPO DIRECT DRIVE: Engineered to operate seamlessly across a wide DC 5.0V-8.4V range. At an 8.4V input, it delivers a robust 9.5 kgf·cm stall torque and a rapid 0.06s/60° transit speed. Driven by a 333Hz digital amplifier and a high-quality JPA NOBLE potentiometer, it maintains a tight 2μs dead band for uncompromising centering precision.","UAV & 450-CLASS HELICOPTER OPTIMIZED: Encased in a CNC-machined full-metal housing (23x12x27.5mm, 24g) that acts as a structural heatsink. Purpose-built for space-constrained airframes, it serves as a highly reliable cyclic or tail servo for 450-class helicopters, and provides authoritative control surface actuation for fixed-wing aircraft, eVTOLs, and professional robotics."]
