Designed specifically for high-performance RC micro/mini helicopters, 450-class cyclics, and agile fixed-wing aircraft, the KST DS315MG V8.0 mini digital servo delivers exceptional holding torque and blistering transit speeds in an ultra-compact 20g package. Featuring a high-response 12mm coreless motor, hardened steel gear train, and native 2S LiPo high-voltage compatibility (4.8V–8.4V), it ensures razor-sharp cyclic authority and precise centering under intense aerodynamic stress.

Key Features

• 12mm Coreless Motor: Instant throttle response, linear acceleration, and ultra-low latency control.
• High-Voltage Operation: Direct 2S LiPo capable (4.8V–8.4V), eliminating the need for dedicated voltage regulators.
• Hardened Steel Geartrain: Dual ball-bearing supported metal drive train engineered for zero backlash and superior crash resistance.
• Full CNC Aluminum Casing: Rugged protection and rapid thermal dissipation during aggressive 3D maneuvers.
• Programmable & Soft Start: Customize travel limits and enjoy smooth soft-start protection upon power-up.
