More Voltage = Less Amp Draw?

I know I'm not missing it... :010: ...to increase the voltage you must reduce the kv accordingly. I assumed that would be assumed. :030: hee hee

Well it's just a point I wouldn't assume everybody reading these threads would know to make.

When I first got into this I would've just thought "Oooh, faster motor cool!!" Without first understanding that means higher current draw, lower starting torque, and generally a drop in source voltage as the resistance of the motor starts to drop to that of the internal resistance of the cells.
