Description

Built for 1/8 offroad steering abuse-e-buggy/e-truggy and nitro

1/8 offroad steering is hard on servos: high bite, big tires, heavy landings, and constant impacts. The ST8HV-SR is purpose-built for 1/8 buggy and truggy competition, whether you’re running electric or nitro (HV systems). It’s designed to stay fast, precise, and consistent when the track gets rough and the loads go up.

Super Response feel: fast, clean, and accurate

At the core is an advanced 32-bit microprocessor with XFET-driven output designed for very high resolution speed and accuracy. The result is a direct steering feel that holds a line through chop and ruts, with the kind of response you notice immediately in tight sections and high-speed corrections.

Competition durability you can trust

This servo is built to finish mains:

•   Full CNC aluminum housing for strength, heat management, and case rigidity

•   Extra-strong titanium gears with a hardened steel output gear where it matters most

•    All-new 4-pole long-life brushless motor for smooth power delivery and long service life

HV-ready, SXR compatible, clean install

Run it on 6.0-8.4v (HV) to match your setup-ideal for modern e-buggy/e-truggy power systems and also a strong fit for nitro electronics. Its Sanwa SXR compatible, uses a 25T spline, and includes a stealth black 18cm wiring for a clean, professional install.
