I'm at a 72mm roll out right now. I have been as high as 111 but obviously that doesn't work. The setup that Randy posted was what I started with with standard, zero, and maxxed motor timing. I have also tried Maxxed, mid, and zero esc timing. Tried max turbo, mid, and zero.
I have put the set up that Randy posted back on. I am using a Tekin 17.5 with all this right now.
