The problem with that solution is the amp output of the regulator. Higher end servos can sometimes pull around 5-7 amps so you would need a more beefy regulator, something like the castle ones.

Right, I would also recommend a castle bec 2.0 it can handle it all, from 6 to 58v and 15 amps. They're great.
