Jacob’s Ladder [Ours des Prairies] Group 4, Video Footage: A, B, C, D, E
The JACOB’S LADDER is a continuous series of transitions between a half BACKSPIN rotation and a half LAZY
SUSAN. Each “rung” of the ladder consists of one set of the two alternating rotations. The direction of the
rotations does not matter. The trick is entered from either a FADE or a TURTLE. If it is entered from a FADE (belly
up, nose toward the pilot), the kite is rotated approximately 180° so that it is belly up, nose away as in a TURTLE,
but with the lines still over the leading edges and coming from under the kite. The kite is then rolled on the pitch
axis so that the nose swings down and around a full 360°, into a true TURTLE. The kite is then rotated
approximately 180°, so that it is belly up, nose toward the pilot as in a FADE, but with the lines still over the
trailing edge and coming from underneath. Finally the kite is rolled again on the pitch axis so that the nose
swings up and around a full 360°, into a true FADE. This entire sequence constitutes one full rung of JACOB’S
LADDER. (If the trick is entered from a TURTLE, it starts with a half LAZY SUSAN and the alternating sequence
continues as just described.) The kite must complete three full rungs of the ladder. The smoothness of the
transitions between positions is crucial to the quality of the trick. The method and direction of entry and exit do
KEY ELEMENTS: ►Minimum 3 full rungs.
You mods are such rules wonks. Those TP-USA guys must have had a real stick up their arse to get so technical about this stuff.
