Interested in the actual wind speed you fellows have used the ;
Speed 2/i0mtr. & 13 mtr. kites .
The german wind speeds are interesting which I feel are on flat water ,est.85kilo person .I own the P3/13&17 which are awsume kites and are wanting to compare the actual / usable wind speed ratings of both kites.
Good one for you to answer Ian Y.( The Flysurfer Man )

Jeff,

I found the foilzone comment to be accurate on the 10m Speed2 being around 12-22knots with best being around 15-18knots. I find using the trim on this kite doesn't seem to make much difference when it's at its upper wind range.

I just took out the 6m Psycho3 today in winds that varied at just below 20knots to that gust that registers on all the graphs of around 40knots! The 6m was very easy to handle kite and never felt out of control even though the conditions were extremely gusty. I rode the trim in the max power setting all day.
