Greetings Kolb fans,
The list has been slow so I have an article on Dave Rains flying his
ultralight. Please go to page seven of The Monitor.
To make it Kolb related I also added a link to his Kolb and a link to the
first ever MV fly-in July 2001 ;-)
Enjoy,

I guess I phrased it wrong - our stall speed did not increase 5 mph, it is
just that because our airplane is heavy, it stalls 5 mph faster than yours,
but still slower than before we added the vg's.
And instead of putting lead weights in the nose - we raised the front
stabilizer mount attach point about 3/4"
