Yeah, this question is about as difficult to answer as "how much current will my BL motor pull?". Loading plays a big role. And by "loading", I mean: weight of the vehicle, the bellcrank arm lengths, tire friction (which is less when the tires are moving). etc. And that's assuming the EPA is set right.

I did a test a while back where I hooked up a Hitec HS-5945MG steering servo (180oz-in torque and 0.13 sec speed at 6v) in my Hyper 8 buggy, and measured the current at 6v under typical (moving vehicle) conditions. I saw peaks of 2.4A with an average of 0.6A.
