Presumably you could use an LM7806 regulator for each servo, however given the voltage drop, and your peak current demand estimates some kind of switching power supply might be more efficient. It occurs to me that the Victor speed controllers are effectively a switching voltage supply... at least if you put a nice big capacitor on the output end. Then you could run a little feedback loop to increase the "speed" of the Victor if the voltage dropped a little low, or "slow" it if the voltage got a little high. I'd probably try to avoid reversing it, though.

That is a bit of a hack job... surely there is a more elegant solution available... there has to be a 12v-6v DC to DC switching power supply solution commercially available.
