Servo HCM 488 BB, MG, 12mm Graupner S4078

Servo HCM 488 BB, MG12mm Graupner S4078 Description
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 suitable for Gyro. Not programmable.

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.
