Question

In a brushless motor, is the more Kv beter or worse?

Answer 1

Its better. Basically means more RPM per volt. You need to compare motors that are the same size if your going to see which motor makes more power. In boating, I think your propeller would make the bigger difference in what motor you choose. Also depends on how many volts your running, type of batteries, and the capacity of the batteries.

Answer 2

i think higher kv means more revolutions per volt.

I could be wrong.  My huge huge brushless only pulls 2100kv but can push me around on a skateboard and my little brushless makes 5800kv and winds out till it sounds like it is going to explode, it can't push me around
