I ran the ran QC2 with stock 27 & 19 turn, with foam tire's. I ran 5 2 0.
If that helps. I think the auto brake is more for modified racing applications.
I would also recommend running a capacitor. Great speedo never ever had any trouble out of the 2 I owned. Cant wait to see how the QC3 stands up to the QC2.
I think it was #4 profile I ran in 12th scale.
A Special Thanks to Arno and Rigor for there support...
