40 years ago when I built my first experimental helicopter it was common knowledge that gyro blades would not work on a helicopter. it had been tried even before I started. I do remember a couple helicopters that tried them never really heard the results but one did switch to Hughes 269 blades then to vortech NACA0012. Has to to with a CG shift when feathering them and high collective pressure. As many symetrical blades that are available I would stick with them.
