My BL Revo project

In short, they are both right! CHC's is right from a scientific view. In that a higher voltage will increase current. However, in the context on rc cars it is slightly different. Because when we add voltage we 'gear down' (ie. use a smaller pinion) the motor has to work less hard, and hence we draw less current. This is how squee is also right.

Ah, but I didn't gear down...

There must be a point where the ESC sends an "ideal" signal of pulese where the BL motor operates with the most effieciency, and this ideal range is based on voltage and wind. I'm sure the AC reactive properties of the coils must have something to do with it, but without inductive ratings, and the frequency of the ESC pulese, it's pretty hard to tell.
