2-1 Kite Technology
Kite Technology
2007 has seen a breakthrough in development of the geometry of each specific model to meet each rider's performance requirement. We have focused on the unique demands of each level and rider group and enhanced each model to exceed their expectations.
Planform
With the introduction of swept wingtip designs, supported leading edges and increased depower, planform is critical in determining a kites performance. The figure below illustrates the huge differentiation between the curvature of the leading edges, positioning of the wingtips in relation to the center of effort and trailing edge shape.
Comparisons of the Lift and Reactor show the slightly more traditional shape of the Lift when compared to the wider wingtips and reduced Span to chord ratio of the Reactor.
With the Supported Leading edge kites (DNA, Flow & Halo) a more curved leading edge allows easier relaunch, and works together with the swept wingtip enhancing the depower.

Wingtip Configuration
A closer look at wingtip configuration and the positioning of the front tow point on each design allows you to understand the effect on sheeting, steering and depower.
On Hybrid Kites, the reduced sweep of the wingtip on the DNA and Flow means a pulley system is not required to achieve a given amount of de power. By avoiding the pulleys the steering is more direct with more feedback from the kite, allowing you to "feel" where the kite is in the window. Limiting the curvature of the leading edge reduces the relaunch slightly (although still significantly easier than a C-Kite).
The larger sweep on the Halo's (which offers the best rollover relaunch) requires a 2/1 pulley ratio to ensure the bar remains within the riders reach while allowing maximum sheeting.
A defining factor on the performance difference between the Reactor and Lift is the difference in wingtip size. The wider wingtips on the Reactor allow the kite to turn positively even at extreme angles of attack.

Foil shapes
Foil shapes on each model have been optimized to offer the best compromise of speed and stability based on the rider requirements.
The finer the entry and shallower the draft, the faster the kite is through the air, the easier it goes upwind and the less drag you have from the canopy. By using a deeper draft and placing the C/E further forward (Less fine entry) the kite becomes more stable and generates more low-end power with less rider input.
This can be viewed below as a progression from the DNA as absolute ease of use, to the Reactor on the other extreme for absolute performance.
