Flexifoil Rage
The Rage is the best all-round four-line kite for land traction. Highly stable and controllable the Flexifoil Rage has been developed on the success of the Bullet kite. The Rage can generate serious power in the right wind conditions and yet the kite is still easy to handle. It is ideal for beginners who want to take part in recreational buggying and landboarding, as long as they start in light wind conditions. The kite delivers a strong pull but with reduced lift which makes it less extreme than the Blade and therefore a great introductory traction kite.
Like all Flexifoil kite ranges, each kite is designed individually to ensure the best performance in the wind conditions in which it will be used. For example, the smaller kites have been designed to fly more slowly in strong winds to increase flyer control. The larger kites have been designed to fly and turn faster in lighter winds to get more useable traction out of them. 
-
New planform The planform has been heavily modified. The kite maintains the sweeping leading edge of the Bullet, but has larger wingtips which help the kite to track and turn better. It also has a thinner centre chord depth and more of a hoop shape which helps to improve the stability of the kite.
-
Top quality materials The bridle line for the Rage is made from sleeved Dyneema. This has excellent strength and stretch properties which means the kite maintains its shape in the sky, even in strong wind conditions. We pre-stretch every metre of bridle line in our factory to ensure that the constructional stretch is taken out of the line. We have tested several types of sail material for the Rage and have decided to use Chikara ripstop nylon as it offers the best combination of strength, tear resistance and long-term durability.
-
New reinforcements We have incorporated several new reinforcements into the kite. Most important are the reinforcements around the rib tab points, where the bridle is sewn onto the kites. These can be high load areas and the reinforcements prevent the kite sail from tearing. Also, every internal rib vent has a reinforcement around it to help prevent the ribs from ?blowing out? in the event of a sudden impact.
-
Intelligent design We are
continually developing our design software and we can now model, predict and analyse the actual 3D shape of a kite when it?s in the air and flying. This means we can then shape the panels more accurately so that the kite has less creases and a smoother more accurate profile. This has resulted in a highly aerodynamic wing which helps all performance characteristics of this kite.
-
New size range The size range
now consists of five kites, the 1.8m, 2.5m, 3.5m, 4.7m and 6.0m. These
sizes cover the wind range more completely than before, allowing the
flyer to get out in most wind conditions.
The smaller kites are ideal for lighter riders and high winds. The larger kites are designed for light winds and
heavier flyers.
-
Variable cell numbers The three smallest sizes have 15 cells, and the two larger sizes have 17 cells. The larger kites need to extract as much power from the light winds as possible, and the two extra cells provide a cleaner profile and a more efficient wing. The smaller kites are designed to control the energy of the wind in medium to strong wind conditions.
-
Gauze We built many prototypes both with and without gauze in the leading edge to find out whether it contributed to the performance of the kite. We found the gauze ensured the leading edge of the kite kept its shape better, which allowed us to make the profile of the kite more powerful. Ultimately, the Rages with gauze flew better than those with a fully open vent.
-
Aspect ratio The Rage has a moderate aspect ratio of 3.5 for the smaller sizes, and 3.6 for the larger sizes. This moderate aspect ratio, combined with all the other features make the kite easy to control and maintains high performance.
