The Axis 5 Control System is the 2nd Generation of the first ever control system to feature a 4 line system at the bar with the performance benefits of a 5 line system. The 5th line is actually connected at the top of the mainline, which allows the rider a 4 line SLE style simplicity, and depower, while preserving the shape of the arc and direct performance feel of a 5th line kite.
