Description

The Blue Bird BMS-115WV+ is a the horizonal lug/wingservo verson of the highest torque servo in the very highly regarded Blue Bird BMS-125WV/126WV/127WV range of 10g servos. At 8.4V the BMS-125WV+'s torque is 7.1 kg.cm while still having an excellent speed of 0.09 seconds per 60° of movement.

This new BMS-115WV+ servo is an upgrade to the BMS-115HV by having a wide volage range (1S to 2S LiPo) and dual ball bearings on the main output shaft. This keeps it precise and slop free, with a long service life.

The Blue Bird BMS-115WV+ is a great wide voltage range servo built to a similar space saving form factor as the MKS HV6110. It is similarly precise, with no free play in the geartrain, and it is even more powerful and faster than the competing product. The large output spline is identical to Futaba 25 tooth splines, so replacement output arms are readily available. Note the Futaba compatible output spline is not the same as MKS so the servo cannot be used with most MKS accesories.
