On this day, there was no wind (yes, it's a Hellfish holding itself up).  But that's not the point - the video below is of a Flexifoil Sabre flying in a circular motion, 360 degress, twice.  We tried unsuccessfully to do the same with the Hellfish, but inflato's just don't fly in no-wind (can anyone prove us wrong?*) 
_{*That doesn't involve a car or motor boat...}

Now, before you say "there must be wind" - yes there was, but it was below the speed at which you could feel it, so approx 1-2 knots max is what the kite was flying, with a bit of running around to help it.
