Default Brushless Rotor Sizes

I notice that Novak comes with a 12.3mm rotor stock, and they also offer a 13mm rotor.

other motors like lrp also come with a 12.3mm rotor stock.

speed passion motors offer a 12mm rotor as well as a 13mm rotor...

what affect does this larger & smaller rotors have?

and why is roar limiting rotor size from 12.3-12.5 (i believe that was the numbers)

i understand that in touring car the 13mm rotor makes the novak motor into a performer.

why not limit the rotor size to rotors under 12.5.

Not really...I can tell you that my 13.5 is WAY slower on the straight, even geared up quite a bit...but it's really nice in the infield. It has a really good feel, drag-wise. I get killed on the straight, though. Probably not taking it out anytime soon, though.

I don't know much about ROAR (100% basher) but most racing governing bodies implement rules to a) keep a level playing field b) make it accessible to more people (mainly through cost control - if the winner was decided by who spent the most, no 'average' people would be able to be competitive) c) promote competition (drivers on the track and manufacturers that supply the components).

My guess is the sizes they chose were already in use by several manufacturers, so were already somewhat 'standardised'. But, like I said, I'm only guessing as I have no actual knowledge about ROAR or their criteria...
