Product overview

The FlashHobby BLS4050MED 50KG HV BLS Servo provides programmable digital servo control with a brushless motor, a 32-bit MCU and a 14-bit magnetic encoder. Its PWM digital amplifier supports end point adjustments, direction, fail safe and dead band settings. Motion settings include slower speed adjustment and soft start rate, alongside overload protection, data save/load and program reset functions. Compatibility with Sanwa SSR, NB4 and Futaba modes gives the servo a choice of supported control modes.

Built with helical steel gears and a CNC AL6061 aluminum case, the servo features a diamond-cut aluminum heat sink shell and a water-resistant, waterproof case. Dual ball bearings support the output shaft, which has a 25-tooth spline. The body measures 40x20x40.50mm and weighs 80g±10g without the servo horn. A 300MM connector wire terminates in a JR plug. Operating speed is 0.12sec/60° at 8.4V, 0.09sec/60° at 11.1V and 0.08sec/60° at 12.6V.
