In the turbo bridle
model there is a yoke between the two outhaul legs and the attachment
point (designated here with yellow dot). Effectively the tow-point
is moved down the inhaul leg a distance. This allows tension to
be maintained on all three legs of the bridle no matter what position
the kite is in.
This allows increased
trickability due to the fact that a flier's inputs are applied
to all three contact points on the frame of the kite. It also
improves turning and tracking (straight line flying). As the kite
flies in a straight line the towpoint rocks upwards and in towards
the spine. When a line is pulled to initiate a turn, the other
wing moves away from the flier and the towpoint on that wing moves
back and outwards towards the wingtip which makes the kite spin
more sharply. When the lines are returned to neutral the towpoint
moves back up and in.
