how do i find out what turns my motor is
 

don't flame for sounding like a n00b... i need to find out what turns a brushed motor is ( it's de stickered and there's no markings on the can or endbell... i don't want to put it on my XRS and it be over the 15t limit

any help would be much appreciated guys
(it's brushed by the way)

cheers

take it apart, it maybe written/etched on the stack

mark the can and endbell with a 'sharpie pen or score mark' so you can line them back up in the way they came apart
