Once you get into the delta head with all the parts, I'm not sure there is that much difference in total parts count and or much difference in cost. For sure much less weight, due to the feather servos and mounting brackets.
or assembly time. There is $20 in servo savings alone. I think it comes down to whether or
not you want to DIY your rotor head or not.
It's pretty clear that some builders take great pride in
making as much of the aircraft themselves. Ok for them, but
sometimes advancement in the state of the art comes from
some new enabling technology. I could have done a swashplate
gyrocopter from heli parts a long time ago, it was the availability
of inexpensive molded rotor head parts on the Feda/Hummingbird/Dragonfly
that made making this kind of design economically possible.
I thought that after I had G3PO sorted out that I would go back and make
a tilting head design, but I lost interest. The three bladed tilting head design
is pretty mature, basically unchanged in design since Emilio's ECDC. I can't see
some radical new tilting head design coming down the line, just refinements of
the current design. So I'll stick to swashplates, until I can do an electronic cyclic
control with servo flaps or something. The electronics are there to do this, just need
some tiny actuators....

Mickey, what is the motor down thrust and rotor mast tilt back in the G3PO?
The mast is set at 110° from horizontal (20° from vertical). Downthrust is 0 or 5° depending on the builders choice.
The 5° helps it stay level under power changes.
