The Blue Bird BMS-M15H 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 -H version incorporates two normal servo mounting lugs.

Despite being only 10 mm thick the M15H’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.
