The Dart is made for speed, jumping and of course, flips.
In the beginning of Slingshot wing development, there was one outlier prototype. This model wing was ahead of its time, as many Tony Logosz inventions are. What is now The Dart, ended up in the hands of the Spencer Brothers, a couple of highly talented young Maui riders. The Dart was designed to be the exact opposite of the SlingWing. It was made for speed, jumping and backflips. It has a huge LE (leading edge), a deep draft, and tons of dihedral. It is not a well-behaved wing, (ie. not a beginner wing) and did not drift very well due to both oscillation and the massive LE creating drag. The trailing edge billows like an old-school hang glider and provides a significant power source. The air flowing over the large LE and into the trailing edge billow gives it incredible loft in jumps. Normally such a huge LE would make a wing slow and not very good at going upwind.
The speed difference is immediately noticeable.
The pointy nose and raked back wing tips of the Dart (think fighter jet) shed the vast majority of the headwind and give it a much higher top speed, better acceleration, and good penetration into the wind. Instead of having the entire big LE exposed to the wind and creating drag, the pointed nose and swept back wing tips make it quite aerodynamic, like the wings of a fighter jet that fold back to reduce drag during hypersonice speed.
