Hello robot builders, have you any experience making small, say 6" diameter
maximum, hovercraft?  If so, please post/email your experiences.

I wish to do just this, but my first prototype consisting of a surplus
cooling fan mounted over a hole in a plastic base does not even get off
the ground, and so I am looking to order more powerful fans.  However, some
of the fans are listed with pressure differentials in mmHg, (another maker
lists "static pressure in H2O"), and also they list CFM (cubic feet of air
per minute) up to say about 77 for the small size (max 3" dia) I am looking for.
So, should I go for highest pressure differential, or highest CFM.
The confounding thing is that not all makers list both CFM and pressure, 
sometimes it is one or the other, making comparisons difficult.

Thanks for your help,
