UBEC 4.8V or 6V

Using the 6V vs the 4.8V UBEC will give higher torque and speed from the servos. Is that the only benefit? Are there a down sides to using the 6V UBEC over the more standard 4.8V?

Your input voltage needs to be at least two volts over the output voltage for best results.....

The 6 volt UBEC will make your servos draw more current....of course....the benefit is more torque and speed...

Some higher end digital servoes are not rated for 6v. Futaba tail servos come to mind. Many have been tested ok at 6v on a regulator.

If your servos can take it you might as well enjoy the extra speed and torque. It's a nice way of waking up some older, tired, gear you have lying around.
