4. Lay the mylar pockets flat so as to avoid creasing the mylar when you fold over the rear portio
of the sail. Replace the sail ties loosely, zip up the bag, and carefully fold the rear of the sail over
against the front.
Remounting the rear leading edges
1. Set the glider on its back (upside down). Unfold the glider, open the bag and lay the sail out full
length. Make sure you are mounting the correct leading edge rear into the correct front (check the
"right" / "left" designation) and remember that left and right are reversed when the glider is lying
upside down, on its back.
2. Wipe the forward six inches of the rear leading edge with a clean cloth to remove any dirt or grit.
3. Slide the rear leading edge tube into the sail and then into the front leading edge, as far as it will
go until you encounter a hard stop. This will be the forward edge of the rear leading edge contact-
ing the the front leading edge.
4. Rotate the rear leading edge so that the washout tube receptacle faces inwards, towards the oppo-
site leading edge and "down" towards the ground (upwards relative to the glider) while maintain-
ing forward pressure on the rear leading edge. Somewhere in this range of orientation, the hole
through the front leading edge sleeve will line up with the corresponding hole in the rear leading
edge. Install the clevis pin with the head in the forward and the safety on the back of the leading
edge. Pull the sail down the leading edge.
5. Remount the sail to the rear leading edge, making sure to align the inner sail mount webbing
(NOT the outer handle webbing) squarely in the slot and attach the securing velcros. Verify that
the sail is oriented properly – the hole in the bottom surface for the washout tube should align
with the washout receptacle.
You may find it helpful to use a large, flat bladed screw driver to pry the sail mount webbing over
the end of the leading edge tube and into the slot. Take care not to damage the webbing. Alternately,
first remove the sail mount screws located at the front of each leading edge to release the tension. The
sail mount screws may be difficult to replace until after the glider is completely assembled. Spread
the wings carefully and incrementally while pulling the sail forward at the nose during assembly to
prevent damage to the sail.
Alpha Set-Up Procedure
The Alpha has not been designed to be set up while flat on the ground, or to be laid flat on the ground
after set-up – the geometry of the airframe, particularly on the 210, does not allow this. Use the fol-
lowing procedure to set up the Alpha.
1. With the glider in the bag, lay the glider on the ground, zipper up, with the nose into the wind. If
there is more than five mph of wind, or if the wind is gusty, turn the glider slightly more than 90
degrees to the wind direction.
2. Undo the zipper, remove the battens, and remove the control bar bag.
