  •  Brushless servo motors consistently provide more torque and power per gram of motor weight, while simultaneously being more efficient than either their brushed or coreless counterparts. Brushless servo motors are extremely tough and precise. They excell at relentless, cyclic, full speed direction reversals, handling them with ease. A very desirable characteristic for a servo motor. 

    The B4's brushless motor spins titanium and aluminum gears that are supported by bronze bushings and dual ball bearings on the output shaft. The main body of the servo is machined from aluminum and houses the motor, potentiometer and PWM / ESC board.
