Noob Brushless Motor Question

[Steve]

On the brushless motors, you have choices of say 3900kV, 4500kV, 5700kV and so on.
Besides gulping more energy, what do you gain with the higher kV?
Higher RPM's [top speed], torque, both and/or something else?
Thanks,

This video has a lot more information on it than you asked for so I skipped ahead to the bit you asked about. If you're new to all this, I suggest that you watch this whole video. Enjoy!

Edit: Well, it looks like the forum won't allow me to skip ahead for you so just scrub forward to 11:46 in the video.

Thx Skaxis, I forgot to check Horizon for help.
Their battery videos and tutorials were a big help.
Good stuff!
