leading edge into the front leading edge, rotating as necessary, until the spring button in the middle
leading edge engages securely into the holes in the front leading edge (fig. 48). Repeat for another half
wing.
Connect the rear leading edge with the middle leading edge. Align both tubes and slide the rear leading
edge into the middle leading edge, rotating as necessary, until the slot in the rear leading edge engages
securely into the clevis pin in the middle leading edge. When the rear leading edge is fully engaged, you
will not be able to rotate it. Repeat for another half wing (fig. 49).
4. Identify crossbar tubes as to left and right, checking the “right” / “left” markings, they have to be on top
of the tubes.
Align front and rear crossbar tubes and slide the rear crossbar forward, rotating as necessary, until the
spring button in the rear crossbar engages securely into the holes in the front crossbar. When the rear
crossbar tube is fully engaged, you will not be able to rotate it.
5. Position the crossbar on top of the frame so that the central unit of the crossbar is on the keel tube and
crossbar tubes are along the leading edges. Set the pullback wire inside the kingpost channel and
connect it with the appropriate rubber cord using a carabiner.
6. Remove protection bag from the control frame. Unwind all wires and identify them as to front, rear and
side. Check the wires are not damaged or tangled. Carefully inspect Nicopress sleeves and wires near
Nicopress sleeves: there should be no damage nor visible deformation.
At this stage the frame is basically assembled and ready to install the sail.

7. Install the Mylar inserts in the sail (if they have been removed before). Make sure you install it right side
up; the slit edge is at the front and on the bottom. The easiest way to install the Mylar is to push it into the
pocket using a long lofting batten attached to the end of the Mylar insert, which is first inserted in the
pocket.
You will have to stop from time to time to make sure the Mylar is properly lying flat in the pocket. Do not
push the Mylar too far into the pocket. Make sure there are no folds in the Mylar, especially at the tips.
Make sure the Mylar wraps in the proper direction to follow the sail around the leading edge as it enters
the pocket.
8. Position the sail on the floor with the keel pocket down and the wings folded over so that the leading
edges lie along the length of the root line, with the Mylar pockets lying on top.
9. The frame is most easily inserted into the sail with the rear leading edges installed. Rotate the washout
struts forward, towards the nose (fig. 50).
