Futaba BLS373SV Servo - HV Brushless S-Bus2 (0.11s/37Kg) (P-SBL373SV)

The BLS373SV is an extremely high specification HV servo from Futaba designed with 1/5 car racing in mind. It supports the ultra-fast SR (Super Response) mode used in the T7PX transmitter for the best reaction and 'feel' available. It is programmable (using the optional CIU-2 / CIU-3 USB adapter) and is compatible with both S.Bus and S.Bus2 systems. The final gear and output horn splines are machined from strong stainless steel for extreme durability in demanding situations. To cope with the extreme torque on offer the case was re-designed to include extra bracing for the output shaft. The electric motor is brushless to produce both speed and torque while simultaneously increasing the reliability and life. The BLS373SV was designed for high-voltage power and can be used with a 2S LiPo battery directly to extract the highest performance levels.
