Default 13.5 & 17.5 motor?

What are or can a motor company do to a 13.5 or 17.5 motor to make them faster for 1/12 scale or sedan?
Is buying a tuned motor faster than an OEM shelf motor? Why?
What are the motor tuners able or allowed to do under roar rules and is it worth the cost?
Thanks

We offer our Ballistic 13.5 and 17.5 with graded (12.3mm legal) rotors and ceramic bearings, which are allowed under ROAR spec guidelines. But, we do not advertise that they are "faster". Spec is pretty much spec. All of our BL motors are designed, built and serviced here in Irvine, CA.

Hi Brian, for 1s in 1/12th the are playing with rotor strengths. Other than that the tuners are looking for the best numbers with the stators and the rotors and putting it all togeather from there. Some will put in ceramic bearings. Thats about it, so your chances of getting a good motor off the shelf is a possibility, (less the bearings). Its pretty much a crap shoot, where with a "tuned" motor they have probably weeded out the real turkey motors.

BB, I am running stock Epic Duo 3 from Stormer for $64.95 and running against many other "Tuned" Duo 3 that they paid $30.00 more for and I don't believe i am getting out motored by any of them. I would say save your money.

I'm running a X-12 17.5 right now with a Tekin RS Pro (1/12). I find it hard to keep up in the infield with the other guys running Novak or Trinity based motors. I've spent a lot of time on RC Tech reading about the X-12 17.5 and trying to get it geared right, but I may take a chance now on the Trinity or Novak motors.

Are you running in a 1s lipo class or a 2s lipo class?

I run a 13.5 Duo3 in my WGT car and have found it to have a bit more rip in the infield and it loves the timing and turbo down the straights. Seems more responsive to timing advance and runs a bit cooler than the D3.

Been very happy with them so far.
