Oh, and I only used two regulators instead of 3 because each are rated at 1 amp, and I am only driving 2 servos.
Yes, it looks to be an effective circuit. But keep in mind that when a project is portable and battery based, duration of the batteries is an important and perhaps expensive goal and the use of older linear voltage regulators is costing extra money in either less duration or requiring a larger mAH rated battery pack then one might otherwise require. Switching regulators should certainly be the first preferred method considered in this day and age.For example just using one each of these switching regulators for each servo is a pretty cost effective and certainly more battery efficient way to go:http://www.ebay.com/itm/251066005460?ssPageName=STRK:MEWAX:IT&_trksid=p3984.m1423.l2649Lefty
