What do you think about making a variable pitch quad with Trex 600 tail rotor assambly parts.
It's using a outrunner motor and a servo for each 70cm blade.
It's also for sale(around 400$)
why would you want 4 motors AND 4 servos?
the only advantage of a variable pitch quad is that you only need one motor
I think that it has the potential to fly well and be very efficient in flight.
But... One of the main reason people started experimenting with quads is that they are mechanical simpler then a helicopter. And much cheaper and easier to build. If you are willing to put up with the complexity and expense of using helicopter parts, then there is no need for a quad. If we are honest a helicopter flies better, has better efficiency, more lift and is more stable then a quad. Especially in bad weather conditions.

And instant reaction to control input. Not that a "plain" quad takes long, but there is a difference.
"And instant reaction to control input."
i thought that ESCs react faster than standard servos, don't they?
Currently building a variable pitch quad - yes changing pitch is a lot simpler than ramping the speed up and down. If you disagree, then come back to me when you can stay in the air for more than one hour.
Performance - capable of producing complex aerobatic manuevers beyond even the most skilled Trex helicopter pilot. A properly designed VPQR will be able to do more than what the guys at G.R.A.S.P. can do with their quads.
