how does brushless motor rating work with the kV the lower the number the faster like how brushed motors are rated or the higher the kV the faster?

kv=rpm/volt The short explanation is the higher the kv the faster it will go on a given voltage. The longer answer starts with first realizing that all winds of a particular motor have the same potential but different ways of getting there.

The kV rating of a motor tells you how many thousand RPM the motor will spin per one volt. For example, the Novak SS5800 motor (5800 kV rating) will spin at around 42,000 RPM when at full throttle when powered by a 6 cell NiMH pack (assuming 1.2V per cell).

5800 isn't its kv according to Novak (although that's what they rated it at when it first came out). It's 5,000 now (or was the whole time..or something?). Anyways.....yeah.... :p ;) :D

How very consistent :confused: :D

I know right? :rolleyes: Could I be any more confused with my Novaks?!?!:p:D (now I know why my SS ESC got so friggin hot before I put a fan on it too....the 5800 is apparently rated at 225 watts, which is the max for the SS ESC......DOH!)
