Yes, you are both right. But I was actually referring the dual rate numbers they recommend as posted below. I would lower them on down some if you are new to CP helis, for instance, rather than 85% on elevator and aileron, try 70%, with 30% expo. And for idle up, try the 85%. I don't even run 100% in idle up, for sport flying and not hard 3D, I just don't need that kind of response.
Also, I was wrong, the DX6i settings are on page 6.

RUDD 0 100% INH
