All interesting stuff, but the fact remains that you can pull a lot more amps than you think when changing a surface's direction even if only momentaraly, avaraging out those peaks does not give you the data you need, some batteries have too high an internal resistance to allow the power needed, using A123 batteries goes a long way to helping this on a simple sport jet, I have no boubt that the Weatronics and Power Box's have their place in the high end airframes, but I and 95% of the rest of us don't scale to these heights.

On my 2.5M 3D Yak, if I wack the sticks into the corners and stir it all around the peak reading on my Watt meter is over 15amps that is stationary on the ground, and none of the surface's are binding or the servo's reaching the end of travel, hate to think what it pulls in the air with those large surface's, jets don't pull as much, but its worth taking into consideration and not poo pooing it as a myth.
