Say Captain, would you know if the l/r channel on two-channel r/c cars tends to output less current than the drive channel?

Seems to me it would take a lot less current to turn the wheels or keep them turned, than to drive. But I'm not sure.

I'm hoping it's fairly typical the l/r output current is about the same. I just can't reduce friction enough on my improvised rudder "servo" rod path.
