Futaba BLS 172SV Brushless Digital, SBus-2, HV

The ultra-powerful servo with an incredible torque of 370 Ncm. Programmable S.BUS brushless high-voltage (HV) servo for direct operation with 2S LiPo batteries. The very robust metal gear is supported by four bearings, and the housing is secured with six screws to handle the enormous forces. The central part of the housing is made of aluminum, which increases gear stability while also aiding in motor cooling.

Despite the extremely high torque, the servo is very fast with a response time of 0.082 seconds per 45°. It is ideally suited for operating the flaps of large model aircraft. However, it can also be used in other applications where a very high torque is required, such as in the steering of 1/5 scale cars.
