Hi guys, I have a doubt. When I read some topics I find a very different evaluation about kite range.
I know from saling studies that the "density" of the air can influence the "strongness" of the wind, so at the same wind velocity there is a different range of the same kite if you are in equator or in less hot countries (where air density is minor).
Range kite reported in official brand website ... Where is referred to?
You are right, there are difference in "power" with different temperatures indeed
But regarding windcharts it does not matter at all, as they are so personal biased and only a very very rough estimation, based often on different non clarified grounds.
In other words: Windchart/range charts are so different and can no be compared, so the difference the air temperature gives, is negletable compared.
You could say that many range charts are either "off", or at least not useable when you dont know the given conditions.
That being said, they are still a fine guide to find approximately where the kite has its sweetspot with a given weight rider and board
You could see this old thread: http://www.kiteforum.com/viewtopic.php?f=1&t=5159&start=10

I would estimate most charts to be in the neighbourhood 25C / 75F if one should have a guess.
