Reinstalling the sail on the frame
1. Install the Mylar in the sail. 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. A small diam-
eter pin on the end of the lofting batten placed through a small hole in the end of the Mylar insert
allows you to push the Mylar into the sail and remove the batten while leaving the Mylar in place.
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, espe-
cially 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.
2. Install the transverse battens in the sail.
3. Position the sail on the floor with the keel pocket up 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.
4. The frame is most easily inserted without the rear leading edges installed, and without the inboard
sprogs attached.
5. Position the frame with the bottom of the noseplate facing up and with the rear end of the leading edges
at the nose of the sail. Slide the frame into the sail through the open bottom surface zipper, making sure
that the leading edges of the frame pass properly into the leading edge pockets of the sail and don’t get
caught at the rear of the bottom surface near the root. As you feed the frame slowly into the sail, check
periodically to see that none of the hardware is snagging on the sail or internal sail ribs.
6. After the frame is fully installed, mount the webbing anchor strap to the rear leading edge with the
clevis pin located 5" from the end of the leading edge. Make sure the strap is properly oriented on
the bottom of the leading edge tube (which is on top with the glider upside down) and that the
strap is not wrapped around the tube. (See the section at the beginning of the manual about
reassembly after shipping.)
7. Reconnect the bottom surface center zipper at the nose, zip part way up, and install a new secur-
ing zip tie at the nose.
8. Install the rear leading edges (see the section on reinstalling the rear leading edges after shipping
at the beginning of this manual.)
10. Install the screws to mount the sail to the front of the leading edges.
11. Insert the top and bottom side wires into the sail and attach to the crossbar, making sure that no
cable is wrapped around a leading edge or crossbar, and that no thimbles are cocked or twisted. Pull
the top front wire out through the hole in the sail.
12. Bolt the bottom rear wires and sail retainer webbing strap to the rear of the keel.
13. Feed the sweep wire through the keel pocket.
14. Flip the glider up onto the control bar. Mount the kingpost to the keel, and attach the top front wire
to the kingpost.
15. Spread the wings slowly and carefully, making sure that the sail rides forward as necessary at the
nose without catching. Be careful: you can easily tear the sail open at the nose at this point.
