The KST MS3509 has a backlash-free, precise metal gear and high centering precision. With a powerful brushless motor, the KST MS3509 is ideal for RC large scale airplanes where fast and precise control is required. The motor of the KST servo can be loaded with up to 32Kgf.cm. The high-quality, all-aluminum housing can be mounted precisely and ensures good heat dissipation.

KST servos of the MS series are equipped with a non-contact, wear-free magnet positioning system. This replaces the potentiometer system with sliding contact.
