Lipo reciever battery

[RC-Monster Mike]

The UBEC is a rated for 3 amps continuos, I think. 4 digital servos under constant draw could give it a workout, but will all four be under constant draw? I think you could get a regulator of some kind to step down the LiPo voltage to a constant 6 volts. I have seen something like this somewhere (FMA perhaps?).
