SRT BHX2S Digital Low-Profile HV Brushless Servo, 180 mm Lead

The SRT BHX2S is a digital HV brushless servo in a flat design for 1/10 on-road cars. It also suits scale and animatronics projects. The low case height fits tight mounting spaces, and the 180 mm lead reaches receivers mounted further away. The servo is designed for high-voltage systems and is programmable.
