I purchased a copy too, still getting the hang of the FFB... I can feel things happening but I don't know how to react.
Is it normal for the brakes to be very sensitive out of the box? I have a DFGT so the pedals aren't great, but it seems like under any circumstances, I can lock the FF 1600's fronts up in the first 20% of travel. It's just hard to tell what is part of the realism, and what means the control configuration should be tweaked.
