Hi,



I found a couple of links you may like to follow...



http://www.hoverclubofamerica.org/fo...php?showtopic= 1232



The last message (as it stands now) has an interesting photo of an Australian hovercraft with a shaped splitter.



http://www.whalepower.com/drupal/



shows new fan designs based on a whale flipper...



though I'm a bit sceptical as the guy that designed it is alegedly Frank E. Fish!



There's another thread on the hoverclubofamerica forum with photos of a new curver and ridged blade.



Regards

Peter
