The HCM 488 BB MG features an optimised 7.4 V coreless motor and boasts the highest torque in its class, at 37 N/cm at a speed of 0.03 s/40°. The technology with low bandwidth by Graupner/SJ provide an assurance of reliable high-quality power. The heatsink housing reduces operating temperatures and thus extends service lives.
The servo is ideal for the swashplate and tail rotor on helicopters with rotor blades up to 360 mm.
Not programmable.

  • Coreless motor
  • Aluminium body
  • Direct operation with 2-cell LiPo batteries
  • Digital servo with dynamic torque, outstanding speed, excellent response characteristics and holding torque
  • Programmable
  • 2048 high resolution
  • Bandwidth 20Hz~400Hz
  • 12-bit processing in the circuit
  • Operating voltage range 4.8 ... 8.4 V
  • Ball bearings
  • Metal gearbox

High-voltage coreless servo (HCM)
  • High-voltage, 2-cell LiPo batteries provide a direct power supply. This is the new product range from the digital servo segment, HCM (high-voltage coreless servo).
  • With a maximum permissible operating voltage of 8.4V, the new battery technology can be used without reservation. Naturally, these servos can also be operated with a conventional 6.0 V supply. The very best production quality tops off this line of our servos.
