KST DS215MG Servo – 3.7Kg.cm 0.05s 20.0g 12mm

The KST DS215MG HV servo is an amazingly powerful and fast metal cased high voltage servo designed to be run directly from a 2S LiPo without needing a regulator. With 3.7 kg.cm of torque, and a rotational velocity of 0.05 sec/60° it combines exceptional power with great precision and market leading speed.

Weighing only 19.5 g it is a great servo for glider elevator & rudder and heli cyclic & tail rotor. Also popular on RC EDF jets. The KST DS215MG HV is designed for use with a 2S LiFe or 2S LiPo battery. Do not use on a 5V supply. It is the high voltage replacement of the acclaimed KST DS115MG servo.
