So, I have acquired (2) D4 motors so far. I'm running three different classes. So, I am getting more, for different tracks , cars etc. Etc.

And I am curious as to which rotors come in which motors? I know there are several rotors available!

What rotor size is in the D4 6.5t?

What rotor is in a D4 10.5 certified?

U can look right in the bottom and see the color.should be a purple 12.3

I have not received them yet lol. They will be here tomorrow or Friday.

Is 12.3mm standard for all D4's
