1. A different horse

2. More horses!

Yes, if the KV changes, you've changed "horses" and the draw will be different for the same work done. It's not as over your head as you think! :)

Artur: When you apply more volts, you get more RPM, up to the limit of the work the motor is able to do. It's the same analogy with the horse, you'll only get so much out of the motor, regardless of what you do.

I will make it simple...

If you get light bulb rated at 12V and apply 16V you won't get more light but it will draw more amps and won't last long. Why? Because of fixed resistance. But how much light it will produce will be based on how big is the light bulb. Now apply the same to the motor...
