I was going to say sikes is a member here and he signed on for a minute this afternoon so I didn't bother waiting to see his post. I thought he was going to say.
"I got some rotors that castle shipped out during the big 1/8th motor sale; because they had shipped 1717's with a 6mm shaft instead of a 5mm shaft. But I liked the 6mm shaft and have sold the motors and had these left over. "

Kv rating is a result of the number of turns in the wind.
