Dave Santos posted this file on Yahoo forum some years ago:
an expected advantage can be avoiding rotating to face the wind direction, acting on the bridle.
Last days I experimented this ugly round parachute as a kite. But a parachute without holes is perhaps not as stable as a parasail with slots for what I saw, or the altitude was too low to avoid turbulence. A kite lifter like Peter Lynn’s single skin pilot-kite would perhaps be better than a parachute if it is quite round in order to face any wind directions without rotating, but losing also some stability (?). For this I prefer avoid implementing tails or cones.
This parachute was realized using XF-film. The wind speed was 6 to 12 m/s.
