KST FZ589 Digital Metal Gear HV Mini Servo 8Kgf.cm 0.10sec
The KST FZ589 Digital Metal Gear HV Mini Servo is a mini HV servo for RC gliders and helicopters. KST positions FZ589 as a smooth, high-torque mini servo for applications that need accurate control in a compact 35.5mm case.
Verified KST data lists a DC 6.0V-8.4V voltage range, up to 8Kgf.cm torque at 8.4V, and 0.10sec/60deg speed at 8.4V. It uses a coreless DC motor, metal/hardened steel gear construction, potentiometer feedback, and 2 ball bearings.
The 35.5 x 15 x 32.5mm case, about 40g weight, and +/-45deg travel setup make FZ589 a practical HV mini-servo option for glider, helicopter, and compact RC mechanisms.
