This is the JR DS398HV High Voltage Digital Precision Metal Gear Thin Wing Servo, and is intended for airplane use or any application that requires a thin micro servo. In addition, this servo includes servo horns and hardware, and includes a three year limited manufacturer warranty. Since this servo is high voltage it can withstand the 7.4 voltage from a LiPo battery pack without a regulator, and while retaining comparable specifications to the DS398 non high voltage servo.

The DS398HV Thin Wing Servo offers class leading holding torque, zero deadband, and JR's legendary high resolution in a package that's ideal for high-performance sailplanes and electrics. By re-engineering certain internal components JR has improved upon the precision of the previous generation DS378 servo to give the DS398HV the performance advantage JR customers demand.
