Check out the new improved Power HD B4S Brushless Servo - 32kg/cm (444.4 oz/in), 0.065sec 8.4V - (Super High Speed and SR/SXR/SSR/SUR/SFR Compatible)

The Power HD B4s high voltage servos are made with brushless technology. 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 excel at relentless, cyclic, full speed direction reversals, handling them with ease. A very desirable characteristic for a servo motor.

The brushless motor spins titanium and steel 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.

These servos are lighter, more torque and perform better than the previous B4 series. They run cooler and quieter and with less vibration - because there are no brush arcings, the radio frequency interference and electronic noise is also significantly reduced.The full CNC aluminum housing, HV and the new brushless technology gives you the best strength and speed while being incredibly efficient and long lasting.

The SR/SXR/SSR/SUR/SFR multi-mode competition-level servo, overcomes the issues of incompatibility between the multi-branded models. Designed with the convenience of "Automatic Matching" that allows you to plug and use immediately without the need to be tied to the same brand.

So now the only question is - why are you still reading this? Go buy your Power HD B4S HV servos before they're gone!
