Too much Vodka .. resulting in the late night spelling of KV :D

:laughing3:  :cherry:

From: http://www.teamnovak.com/products/brush ... s5800.html

"This number is the motor voltage constant expressed in RPM/Volt. This indicates how fast the motor will turn for a given voltage (given there is no internal resistance). As an example, the SS5800's Kv rating is 5,800 RPM/Volt. Therefore, if a 6.0-volt battery pack is used, the SS5800's RPM would be 34,800 (6.0 x 5,800). "

So in theory, different motors with the same KV rating will have the same RPM at the same drive (pack) voltage. But the different motor may produce different amounts of torque, making them different on the track.

In general the number of turns on a motor is used for spec. in different racing classes.

Many thanks for the advice Mick, it was extremely helpful.
