nice video. I have hills like that around here. Makes me wonder a little. I missed the significance of the helicopter though.lynx69 - 26-10-2009 at 02:56 PM
Kool vid. Great hang time going down the hill side but how about going back up? I guess I am too lazy. I guess the helicopter is symbollic of the
hovering hangtime. Probably could have not shown the guy's shoulder tore up at the end though.lad - 26-10-2009 at 02:57 PM
I wouldn't even dream of going that high and far w/o being armored up!redtailin - 26-10-2009 at 08:58 PM
Not to sure how the air evolution 'flaps' work specifically, but Im thinking its the same concept as the flysurfer 'jetflaps'. Then you pull on the
bar you are not only changing the angle of attack of the kite, but also changing the shape with these kites. When you change the shape, it allows air
to flow through cutouts on the trailing edge of the kite (flaps, if you will). When this happens the chord line of the kite will increase which will
help increase lift, but the most effective bit is the increased airflow over the trailing edge, which adds energy to the boundary layer. When that
happens the boundary layer will tend to stay attached to a higher angle of attack, allowing a higher angle of attack with less stalling = more lift.
Again, not positive on the specifics for this kite, but I believe thats what they are getting at. There is a video out by flysurfer that explains it
partially, I believe its a promo for the Psycho 4's....hope that helpscarltb - 27-10-2009 at 01:15 AM
Thats a vid of a few guys i know from wales. the guy at the end is pete(wenglish on other forums) and he hurt his shoulder on the kite loop right at
the end.
the wind direction when you are hill jumping is straight up the hill and you fall down the hill into the wind, so getting back up the hill is easy.
