how come the parachute does not get tangled up?
Swivels. Plus a long enough line on the harness that it probably doesn't need swivels.
I want one.
It could be that the centripetal force and the air resistance inside the parachute keeps it from tangling.
but would be banned in any western country by the military, air traffic control, homeland security and a bunch of other killjoy govt departments ;)
doesn't need that the lines from the parachute cone to a central point then a single line down to the unit
a swivel, as suggested, at that point, would be the easiest way to stop the chute lines from tangling :)
perspective. it looks it is spining horizontal but it´s already vertical. The clibing seems cool, the spining creats the efect for verticality
Maybe. But even spinning around a horizontal axis would not entangle the rope, if it attaches to a point on that axis at the circumference. Just like a gyro spinning around an horizontal axis, which is supported by a rope on just one side.
