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.

excellent value and qualiry

bought these for flaps and ailerons and find them to be precise and more than suitable. very easy to blow the budget when buying servos i went for a more budget focus option from the servos recommended for the orion but have no regrets and would buy again. have to say every product i have bought from hyperflight has been quality. the rated torque is very high compared to similar small servos and having wide voltage is a bonus for future use

bluebird servos

Very impressed with these little servos and pleased with the price. I have these in an NG2 for elevator and rudder and they are rock solid, happy to recommend them as an alternative to the similar MKS servos. Time will tell.

Best for the money

A very strong reliable servo. I'm a fan of these and the MKS 6110 with these being my go to servo for all my ALES and F5J competition sailplanes.

Great Servo

Appear very good and tight. No slop as yet. Time will tell.

Great little lightweight wing servo

I have these servos in 2 gliders already and go these for an aerotow Jantar 2B. I've used other bluebird servos in numerous other models without issue. Really with their power and centering seems to be very good


 Review by:

Powerful little servo

As advertised. Fast shipping.
Installed in 3.8M F5J sailplane. They operate smoothly with accurate centering... What more can you ask for... longevity... that remains to be seen... So far so good👍🤓
