Questions?? Need a little brushless help

Alright, I have an Rc18t with a SideWinder Micro ESC. I was running a Castle 1/18 6800kv motor but I burned it up. Anyway, I'm in need of a new motor and I'm wondering what motor would be best. From what I've gathered, a bigger can in better because they don't overheat as easily. However, bigger cans also have lower kv ratings thus lower rpms. So I guess this brings it down to two questions. Why do bigger motors have lower kv ratings and which motors work best in 1/16 and 1/18 scale cars/trucks?

Motor size and kv ratings are not related.

A 540 sized brushless motor may be rated from a 25.5 down to 2.5, with the same motor can size. It is not the motor can size, but the windings inside.

Hope this helps.
