When elevator authority and split-second response define the difference between a perfect thermal climb and a missed recovery, the KST DS213MG V8.0 micro digital servo delivers. At just 16g and 24.5mm tall, it packs a high-response 12mm coreless motor, hardened metal gear train, and wide-voltage HV operation (4.8V–8.4V) into one of the most compact servo packages available for glider elevator and small RC aircraft applications. With 3.5 kgf.cm of torque and a blazing 0.07s/60° speed at 7.4V, precision and performance are never compromised by size.

Key Features

• 12mm Coreless Motor: High-response coreless design eliminates cogging for instant start-up, ultra-smooth travel, and precise, jitter-free centering at all voltage levels.
• High-Voltage Operation: Wide 4.8V–8.4V range supports NiMH, single-cell LiPo, and 2S LiPo systems — no regulator required.
• Hardened Metal Geartrain: Precision metal gears with dual ball bearing support deliver zero-backlash control authority and long-term durability in repeated high-load elevator applications.
• Ultra-Compact & Lightweight: At 16g and 23 × 12 × 24.5mm, the DS213MG integrates into the tightest glider fuselage and small RC aircraft elevator linkage spaces.
• Wide Travel Angle: ±70° (140° total) default travel provides generous throw range for full-authority elevator and rudder control.
