Check out the new Power HD 0804HV Brushless servos!

These are great to use a throttle servo and can be used in systems with other high voltage servos!

The Power HD 0804HV high voltage servos are made with brushless technology. Now - we've heard about this "brushless" stuff before but it is time to ask the question on all of our minds - why is that so great? Take a brushless motor for example - no brushes in a brushless motor (no kidding...) nor does it have the commutator - instead a small circuit board coordinates the energy delivery to the windings. Think about this technology being used in a power tool - since the electronics communicate directly with the stationary windings the tool can adapt to its surroundings - only using enough juice necessary to accomplish the job. So if you are using a brushless drill to drive a screw into Styrofoam - it will sense the lack of resistance from the foam and pulls only enough charge from the battery that it needs. Whereas a brushed drill will run as fast and hard as it can no matter the job simultaneously wasting your battery life.

"What the heck does that have to do with my servo?" Well now they are incorporating that smart technology into these HD 0804HV high voltage servos - so they are not going to be sucking the life of your Redwing LiFe battery when it doesn't have to - which means not only would you be getting a great and powerful servo - it's smart! Your "LiFe" will thank you.

These servos are high efficiency and perform better. They run cooler and quieter and with less vibration - because there are no brush arcings, the radio frequency interference and electronic noise is significantly reduced.

All aluminum housing, high voltage and the new brushless technology gives you the best strength and speed while being incredibly efficient and long lasting.

So now the only question is - why are you still reading this? Go buy your Power HD 0804HV servos before they're gone!
