The Blue Bird BMS-M15V servo is a ground-breaking new servo from Bluebird. It uses a magnetic contactless position sensor which will never wear out and thus removes the major failure mode of my most RC servos. The case of the -V version incorporates two horizontal mounting lugs for secure mounting in wings and tail services.

Despite being only 10 mm thick the M15V’s torque and speed are both very high making it suitable for all control surfaces on fast gliders and jets. The voltage range goes from 4.5V up to 8.5V, making it perfect for use from electronic speed controls (ESC), 4.8V NiMH or 2S Lipo batteries. The high-quality metal gears are supported on two ball bearings and the servo is driven by a high-quality coreless DC motor. The black case is anodised aircraft grade aluminium alloy, not plastic.

The large output spline is identical to Futaba 25 tooth splines, so replacement output arms are readily available.

Blue Bird BMS-M15V

Excellent servo without potentiometer. Great
flaps for F5J models.

Light, Strong Precise

A very nice wing servo for my new 2.5 m F3F plane.
Light and precise, fast enough.
Futaba spline makes it easy to get sevoarms or LDS output adapters.
A pity that there is not yet a specific complete LDS set.

Comment by:

BMS M15V - a real alternative to KST 08/10 servos

this servo is light, forceful and precise (and poti-less), thus ideal for driving ails and flaps for F5J models
