For me I still think the Emcotec data applies the best. They wired up a plane with 14 digitals (8611's) and recorded ACTUAL in flight current loads.

What is worth noting is that they recodred "normal" loads of around 3.655 amps with a peak of 26.2 amps.

But the hysteresis does not cause the power drain. The load on the servo causes the power drain. You may call the displacement from the commanded position hysteresis but I don't. Hysteresis to me is a fixed displacement caused by the built in characteristics of the material and will occur independent of the load applied and will not cause an increase of the power drain.

Now I see the conflict --
the load causes a unintended hysterisis -That is how I was looking at it
or--"the load causes a hysteresis which results in a high power drain."
better?
On another note
Notwithstanding the arguments for regulated power supplies in models - I simply reject adding devices which heat in power supplies .
The fact that there are now excellent cells which can run unregulated -in any size model- simply eliminates any need for more complexity and possible problem from heat .
The problems I have seen with LiIons and regs (and many regs in general) are all summed up in one word .
HEAT.
battery weight "savings" is a almost non issue anymore.
I have had 42%models which pack 50 ounces of fuel -and a 10 ounce savings (if you will) - is simply not worth consideration in the big picture
On my foamies - I struggle over grams - it is all relative.
