A (train of) parasail(s) as AWES ?

Maneuvers on the ground, like a kite.

First test of 1/3 scale Rogallo chute

Siklóernyő mentőermyő - Vonblon Papillon rogallo (Paragliding reserve/rescue parachute)

Questions: is a Rogallo rescue stable enough for kite use, despite the low (about 30-35 degrees) elevation angle, but sufficient and suitable for AWE use to avoid excessive cosine losses? What happens to its Cd and Cl at different wind speeds?
