Or watch at the bottom of an auto where RPM is low and a lot of collective pitch is being applied - the coning angle is large and easily visible.
As far as the disc tilting, they all do! Just move the cyclic on any type, be it a teetering head or otherwise, and watch the tip path change. Flexing in the blades and attachment hardware, or movement around a hinge, it doesn't really matter - the net result is a tilt of the disc as a whole (which as we all know is a fictitious concept anyway, it's just a number of individual blades doing their thing as they whirl around at ridiculous speeds.)
