Fair enough...and i talk also from experience too...living in a LW world..FloridaToby wrote:In Egypt the kite center had a wind station with max and average winds meassured.
Maybe 4-5m off the ground. There I saw the average 8 knots and just beore I stayed upwind.
BS if you think, I talk experience with the info I had.
Dimitri, you know that no matter how much evidence you throw, they will still whine and bitch about it being impossible. It's a losing battle, especially when you post video evidence. We all know how people like to claim conspiracy and special conditions on video evidence!Dimitri M wrote:Testing the INFINITY V3 prototypes in 20 to 40 knots.
By the way check how low the INFINITY v3 kite is. Plus that day the wind meter of the Kitty Hawk Kites shop was showing around 2.7 to 4.8 mph which it is located on top of the roof which is 40 feet above the ground.
Nonsense. There are kites that fly indoors, in no wind at all.kookfest wrote:"Pump Me Up" is correct. I'm privy to a lot of new kite testing. No kite will stay upwind under about 8 knots, regardless of the board. There is no kite in the world that will even fly in 2-4 knots. People sometimes get confused about kites because of the phenomenon of "gradient". The wind speed at 40ft can be completely different to the speed at ground level.
A couple of knots. Using what little wind gradient there is for half-assed dynamic soaring by working the kite is probably a whole lot more useful.Wikipedia wrote:According to one source, the wind gradient is not significant for sailboats when the wind is over 6 knots (because a wind speed of 10 knots at the surface corresponds to 15 knots at 300 meters, so the change in speed is negligible over the height of a sailboat's mast). According to the same source, the wind increases steadily with height up to about 10 meters in 5 knot winds but less if there is less wind. That source states that in winds with average speeds of six knots or more, the change of speed with height is confined almost entirely to the one or two meters closest to the surface. This is consistent with another source, which shows that the change in wind speed is very small for heights over 2 meters and with a statement by the Australian Government Bureau of Meterology according to which differences can be as little as 5% in unstable air.
