Product Description

The HS-485HB updates the very popular HS-475HB by adding more torque and greater speed. With its top ball bearing, heavy duty, high impact Karbonite™ gears and high performance circuitry, the HS-485HB offers lots of torque and features excellent centering and resolution.

  • Applications: Heli's and Aircraft up to 72” or up to 12lbs when using just one servo per control surface.
  • Note: Be aware that high vibration gas (not glow) engines combined with large contol surfaces and large thows (3D models) can put undue strain on the gears. Metal geared servos are recommended for these applications even if under 12lbs.
  • Warning: Do not use thread lockers on Karbonite geared servo as it will cause the output shaft to fail.
