Two sizes, 400 and 500 Models. The 400 is a 9 cell rectangular planform with a 2.8 to 1 aspect ratio. The 500 is an 11 cell rectangular planform with a 3.15 to 1 aspect ratio. The mains have Zero Permeability top skins. The drogue is attached directly to the passengers' hips bypassing the container and the masters' body. This drogue loading system is designed to avoid most common mistakes and make passenger control less difficult. This is a result of late market entry where we were in a position to learn from the earlier entries and produce a better balanced, easier to use system.
