Servo HCM 870 BB, MG, 20 mm Graupner S4073

Servo HCM 870 BB, MG20 mm Graupner S4073 Description
The HCM 870 BB MG has a 7.4V optimized coreless motor and has a high torque of 32Kg / cm at a speed of 0.1sec / 60 °, leader in its class. The low deadband and programmable digital circuit technology from Graupner/SJ ensure a reliable, excellent performance. The heat sink housing provides for lower operating temperatures and therefore for longer durations.

High-voltage coreless servo (HCM)
High-Voltage, 2-cell LiPo battery direct operation input. Therefor the new product range from the segment of the digital servos, HCM (High Voltage Coreless Servo).
With a maximum operating voltage of 8.4V, the new batteries technology can be used safely. Of course, these servos can be operated with conventional 6.0V. Highest production quality also rounds off this line of our servos.

Info
High-Voltage Servo (HVS) 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 metal housing 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.
