Why do gyros use tilt head rather than swashplate

Power adjustments? I don't see the difference a swashplate over a tilt
head
for cyclic control would make to a gyros rotor system. Care to explain
further?

OTOH, I think that sport gyros today use the tilt rotor hub because it's a
very
simple design, and it works very well. No swashplate and associated
linkages,
not to mention the fact that there's no need for individual feathering
hinges
on the rotor blades themselves. Much less to go wrong and/or maintain.

The K.I.S.S. formula at it's best.

So why not on a helicopter? (Like those old kits I mentioned). I'm assuming
because you'd lose auto-rotation?
