hadn't driven my 12th since snowbirds and I remember why I love 12th scale. Control rules. Got a bd in the car on setting 2 now, 1 didn't have anything with the 7.5 I can fell the difference with setting 2. but still think I'm out in left field.

I ran an X12 6.5 Octa in 12th mod at the Roar Nats with a Tekin RS
47 roll, 25 boost, 12 turbo, 2 dot insert. if that helps any ?
It was plenty quick, and very smooth off the bottom.
Temp never over 130f.
