Removing the Sail from the Airframe and Re-Installing
Many maintenance and repair procedures will require the removal of the sail from the frame. Please
follow these instructions when removing and reinstalling the sail. Please read all the instructions for
each operation before beginning.
Sail removal
You will need an unobstructed area six feet by thirty feet. Make sure the surface is clean. If it is abrasive, like
rough concrete, you should either put down a protective tarp or be extremely careful not to scrape your sail.
1. Lay the glider on its back, unzip and remove the glider bag and put the battens aside. Remove the
control bar bag.
2. Remove the screws which mount the sail at the front of the leading edges. Remove the webbing
zipper stop at the bottom nose area. Completely unzip and separate the bottom surface zipper.
3. Spread the wings slightly. Unroll the sail so as to gain access to the bridle attachment points on the
trailing edge. Push on the bridle cable loop at the bottom of the loop to expand the loop into a
circle, and rotate the plastic ball out one side of the loop to remove it. Disconnect the bridles from
the sail.
4. Dismount the sail from the rear leading edges by removing the clevis pin located five inches
forward of the rear of the leading edge tube. Remove the pin from the sail anchor strap and
reinstall it in the leading edge.
5. Remove the rear leading edges (see the section on "Breaking Down The Rear Leading Edges" at
the beginning of this manual).
6. Unbolt the bottom side wires and top side wires from the crossbar and feed them through the holes and
out of the sail. Unbolt the bottom rear flying wires from the rear keel. Reassemble the hardware removed
onto the bolts in the original order so that it doesn’t get lost. All disassembled assemblies on the glider must
be reassembled in the proper order and orientation. Use the exploded parts diagrams in this manual to help
you.
7. Unbolt the kingpost from the keel, and detach the top front wire from the kingpost.
8. Undo the velcro which holds the front part of the keel pocket together. Slide the frame out
through the open center zipper. If you encounter resistance, stop and find out what is hanging up.
9. If you need to send the sail in to the factory for repair, remove the Mylar and the transverse
battens. The Mylar is removed from the front end of the Mylar pocket. It helps to secure the
opposite end of the sail to something solid, so that you can lay the leading edge out straight and pull
the Mylar straight out of the pocket. If you have trouble getting it to slide out freely, it is probably
because the edge of the Mylar has worked its way into the seam and gotten stuck on the adhesive
seamstick tape. Work your way up and down the leading edge pocket rolling the Mylar away from
the seam until it is free along its entire length.
10. Fold and package the sail carefully if you plan to ship it in for repair. Be sure to include written
instructions of what you want done, your name and a phone number where you can be reached
during the day.
