Upgrade your micro RC car with the GOUP RC 9G Micro Digital Servo, built around precise metal gears for smoother, more reliable steering. This compact unit is designed to fit ARRMA Granite GROM models across 1/18 and 1/14 scales, offering a practical upgrade path for loyal hobbyists who want more responsive control without sacrificing space or weight.

What makes this servo stand out

The heart of this upgrade is its metal gears and digital control, which translate to heightened sensitivity and a crisper response in tight turns and quick direction changes. The 9g form factor keeps weight down while delivering consistent performance, making it a popular choice for compact cars, buggies, and trucks where every gram matters.

  • 9g micro size supports easy installation in tight micro builds without overloading the chassis.
  • Digital servo with metal gears provides smoother, more accurate steering and faster response compared to standard plastic-geared servos.
  • Internal metal gears deliver durability under load, reducing wear during aggressive driving or rough surfaces.
  • 20T aluminum servo horn is included, offering a sturdy, high-precision connection to the steering linkage.
  • Waterproof and rugged construction helps maintain performance in challenging environments and variable weather.
  • ABS shell enhances heat dissipation, contributing to more consistent operation over longer sessions.
  • Built-in temperature, voltage, and blocking protection improves reliability and helps prevent common servo issues.
