DS188HV  High speed, high voltage, super sub-micro servo.

  • Overview

    The JR 188HV servo is the latest sub-micro update for the JR brand. Based on the original and successful DS188 servo, it has a new high-voltage motor allowing it to operate unregulated when using a 2-cell Li-Po or Li-Fe battery or another high-voltage power supply. With the added performance generated by the new HV motor this servo packs quite a punch for its tiny size. Weighing only 6 grams, the DS188HV servo is not only suitable for many hand launch sailplane configurations, but is also very good for indoor foamies and micro helis now available to the market.
