DS589MG V8.0 Mini Digital HV Metal Gear Servo 9.2Kgf.cm 0.08sec for RC Helicopter & Fixed Wing
KST DS589MG High Voltage Servo
The KST DS589MG is a high-voltage metal gear servo designed for helicopter cyclic control and a wide range of fixed-wing RC applications. With a compact 15mm thickness and 40g weight, it offers an excellent balance of size, weight, speed, and torque.
Operating at high voltage, the DS589MG delivers up to 9.2kgf·cm of torque with a fast 0.08 sec/60° speed, providing strong and precise control for demanding RC setups.
The servo features a contactless position sensor for accurate and reliable position feedback, helping maintain smooth and responsive control while reducing wear associated with traditional contact-based sensors.
With its combination of high torque, fast response, compact dimensions, and contactless sensing, the DS589MG is a versatile choice for helicopter cyclic systems, fixed-wing aircraft, and other performance-focused RC applications.
