BMS-M57H Vertical Mount Wing Servo, HV-Digital, Magnetic Sensor, High Torque, Metal Gear, Coreless servo provides huge torque ratings for a servo this size with an ultra precise magnetic hall sensor.

The Blue Bird BMS-M57H servo is a new servo from Bluebird, perfect for RC-Sailplanes-F3J, F3B, F5J, Jets and other wing applications. 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 vertical mounting lugs for secure mounting in wings and tail services.

Despite being only 10 mm thick the M57H’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. Removable pigtail for easier and lighter installation in wings.

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