High-Precision Futaba HPS-CT501 for Tight Builds

The Futaba HPS-CT501 combines S.Bus2 compatibility with a slim footprint for installations where space is limited. Delivering 21kg of torque at 7.4V, it is engineered to give dependable steering and control in compact chassis and scale projects.

Benefits of Brushless Design

This model uses brushless components to increase operating efficiency and endurance compared with conventional servos. The result is smoother motion and fewer service intervals for active hobbyists.

Designed for 7.4V Systems

Rated for 7.4V operation, the HPS-CT501 maintains speed and torque under heavier loads and helps sustain consistent responses during dynamic driving or precise manoeuvres.

Fits Where Space Is Limited

The low-profile housing allows the servo to be tucked into constrained spaces without compromising torque. That compact packaging is ideal for lightweight or scale cars where internal room is at a premium.

Specifications

  • Torque: 21kg @ 7.4V
  • Voltage: 7.4V
  • Compatibility: S.Bus2
  • Type: Brushless, Low-Profile

For model builders seeking a compact servo with genuine torque, the Futaba HPS-CT501 balances small size with strong performance, making it a sensible choice for precise control applications.

Yes, the low-profile form is specifically suited to installations with limited vertical clearance, such as many touring car and scale interiors.
The servo is rated at 7.4V, so a 2S LiPo or a regulated supply matched to that voltage is appropriate for steady operation and full torque output.
Use robust servo horns and secure mounting points to reduce flex and wear. Upgrading linkages to metal parts can further improve longevity under heavy loads.
