Hi mac,

Every servo is different, but if we take a "Standard Servo", under full load, it can draw as much a 700ma @5V (stall current). So if there's a lot of weight that they are trying to lift, 2 servos = 1.4amps, 2.8amps for 4, and a whopping 8.4amps for 12 servo's.

Hungry little boogers.

Even under NO-LOAD conditions, you'd still need 1.9amps for all 12. (160ma each)

Time to break out the Heat Sinks
