To make this work, you'd need either...
1) The ability to adjust camera speed dynamically to keep up with changes to rotor RPM. You'd need a digital camera I think, unless the view finder looked through the shutter too.
2) A helo with an automated rotor RPM, ie autothrottle. All helos would have an ideal rotor RPM for a certain phase of flight, which you could know in advance. The problem with a manual flight control system is that any change to throttle or collective will change RPM, at least a little bit, unless precisely counteracted with the other control. Ground effect and airspeed would probably affect that as well.

With my cheaper Canon DSLR I can control the shutter speed and then also frame rate. Movies are 24-30 fps and there is a recommended shutter speed...think its double the frame rate. I think this person sits out there a lot Rick to practice or test what they need to get it appear motionless.
