Re: What do you make of this?

Ken, the proven design is the one that I saw in the last few minutes
of footage of the video that you were in.  I like the fact that the
WIG could lift off without any forward movement.  What I didn't like
is the two propellers sitting up front obscuring the view of the pilot
and presenting a hazard for anyone to walk into.  Gunther Jorg has
done the tandem wing setup with the propeller in the rear but then he
loses the ability to lift off with no forward movement.  So far, the
animated design is the closest compromise between the two ideas.
Keeping someone out of the propeller is of utmost safety but I am
looking for a no forward movement lift off at the same time.  A
hovercraft does this via the skirt system.  Hopefully a WIG can be
designed skirtless with similar takeoff characteristics of a
hovercraft.
