Ok can someone please break down the difference of the A vs B setting on Cab kites? I had one guy tell me the B setting makes it turn faster and increase bottom end. But that contradicts my Core kite because further back setting (equivalent to Cabs B setting) says slower turning for wakestyle.
I guess it comes down to physics... If the rear line is attached further from the wingtip that translates to me as Slower turning but tilts the kite with a different angle of attack that applies more power with less depower (more low end and perhaps higher boosting?)
Lastly: Does the A vs B Setting really make that much of a difference? And how does the B setting coupled with rear pig tail knot setting compare to A Setting on first knot pig tail setting.
Thanks in advance guys
A setting makes the kite turn quicker and creates less bar pressure
B setting makes the kite turn slower and creates more bar pressure
The angle of attack remains the same regardless of the setting you choose. You change the angle of attack based on the length of your steering lines and flying lines. Shorten your steering lines and you increase the leading edge angle. i.e. the leading edge tilts back more. Lengthen your steering lines and you decrease your leading edge angle. i.e. the leading edge tilts down more.
This is why when you depower your kite loses power. The leading edge is tilting down into the wind and therefore more wind passes over the top of the canopy as opposed to under the canopy which creates more lift.
And to answer your last question the answer is "yes" there is a substantial difference between the two settings and this becomes very apparent in stronger winds.
If you want the most power, best boosting, and best hang time then set it on the B setting and attach your lines on the last knot (the one closest to the kite). This will shorten your steering lines by approximately 3 inches.
If you want the fastest turning and lightest bar pressure then set in on the A setting and attach your lines on the first knot (the one furthest from the kite).
All of the above only applies to a properly tuned bar where all lines are equal length.
Imagine the steering line attachments right behind the front line attachments, and pulling the bar the same amount.. that's what he meant with more AOA.
But Cabrinha's a bit strange with naming their features... with every other company it's 'bar pressure/turning speed' but nooooo Cabrinha has to be special and name it different.
Turning speed can be interpreted multiple ways as well... with the more pressure setting the maximum turning speed is higher, only because of the more time and power it takes to get to that point the kite will turn slower in the end. More responsive though because of the higher tension, that's why some people mistake it for a faster turning kite.
Btw, when you depower there's just as much wind above and under the kite. Difference is the wind on the underside doesn't get deflected downwards as much anymore.
