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 2 m by 9 m (6x30 ft). Make sure the surface is clean. If it is abrasive, 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. Spread the wings slightly. Dismount the sail from the rear leading edges by removing the clevis pin located 100 mm (4'')
forward of the rear of the leading edge tube. Remove the pin from the sail anchor strap and re-install it in the leading edge.
3. Remove the screws that tether the nose part of the sail at the leading edge tube and keel pocket at the rear part of the
keel tube. Remove the rope zipper stop at the bottom nose area. Completely unzip and separate the bottom surface zipper.
Unbolt the upper front wire from the noseplate and feed it through the hole and out of the sail.
4. Remove the rear leading edges (see the section on "Breaking Down The Rear Leading Edges" at the beginning of this
manual).
5. Unbolt the bottom and upper side wires from the crossbar and feed them through the holes and out of the sail. Detach
the bottom and upper rear flying wires from the rear keel.
6. Unbolt the hang loop from the kingpost. Detach the kingpost from the keel tube channel.
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.
7. Slide the frame out through the open center zipper. If you encounter resistance, stop and find out what is hanging up.
8. 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.
9. 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.
RE-INSTALLING 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.
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.
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.
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. Install the rear leading edges (see the section on re-installing the rear leading edges after shipping at the beginning of
this manual.)
