Steerable vs. non-steerable rescue systems
The canopy trim with S-fold, similar to hang gliders, provides a high righting moment. The risk of downplane and stable shear positions are thus prevented.

Disconnecting vs. not disconnecting the main glider
In any case, the canopy trim ensures that the main glider can be easily pulled in with little effort, or even at least unilaterally be released with conventional carabiners, also if it is not disconnected.

Parachutes with headway vs. vertical sinking
Due to the diagonal orientation of the canopy and the trim with longer lines at the trailing edge, the Charly DIAMOND Cross generates a high aerodynamic righting moment. Therefore, there is no tendency for a stable downplane as it is the case for Rogallos with similar forward speed.

Already during the development of the DIAMONDcross, the topic “entanglement of the rescue system with the main glider” was crucial for diverse product details, which have been certified with additional tests far above certification criteria during the summer. The most dangerous situations for a rescue system becoming entangled with the main glider are SAT-like rotations after tangling up. This was simulated by holding collapses.


DIAMOND Cross has a defined forward speed in a diagonal direction with the effect of a significantly reduced sink speed. This results on the one hand in a higher aspect ratio compared to conventional square canopies, those propulsion mainly takes place towards one side, and on the other hand in the asymmetrical airflow of the convex sides of the DIAMONDcross canopy, thereby receiving an ascending forced optimised profile.
