gadget guru - Everything!
Moving, 3D examples would help me understand the concepts of the principles of helicopter flight much more fully - particularly flapping to equality and phase lag. I imagined perhaps a few graphics running concurrently - one showing the whole rotor from above the aircraft, one from the side or rear as appropriate and one showing the aerofoil section with the changes in relative airflow and angle of attack - all changing in sync with the relevant numbers changing too. Nothing much!
I was thinking along the lines of the graphics I have seen
here - they may however be a bit too simplistic for this subject matter, dunno.
pa42 - I think all I have to offer at the moment is what a student in EXTREMELY early stages might want!
