TOPIC:

Is there any visual difference between the two versions of the Dynatech 01R motors?
I know that v1 (9019) means it is a 19x1 0.90mm and the v2 (0017) is a 17x1 1.00mm, but is there a way to tell them apart?

Hey there, I'm assuming you mean your referring to the rotors From memory there are different markings on each, but I can't remember what they are

Which rotor was in it originally? Or were they sold in both versions, pre-mounted?
