TET,
To answer your query. The experimental R44 is due to a conversion. The yaw control is on the cyclic in a twist grip. The pedals are still there and move as well but the pilot destined to fly it is paralysed from the waist down so the feet controls are pointless. It's actually very easy to fly, regardless of people's views on Robinsons, the feel of the yaw with your fingers is much more sensitive than with your Steel Blue boots on....so to speak. It's still under going approval and I'm convinced it will get through. For cynics out there, it's not destined to be flown solo under this system.
Cheers FP
