6. Remove nose cone and release the lower nose wires.

8. Bring the wings closer together making sure to lift the inner washout rods to lie them alongside the 
leading edges. Pull the sail between the leading edge and keel so that it is all above the leading edge. Roll 
it carefully and tuck it inside the leading edge. One side can be rolled and retained with a tie and tip sock 
while the other is being done. 

9. Remove the nose batten if you intend to. Put all the battens into their batten bag.

10. The battens can be stowed at the front of the glider between the leading edges with the curves over the 
nose section. The ties can then be placed round the glider holding the leading edges neatly together. Take 
off the ties holding the sail in place and put them around the whole glider in the normal way. 

11. Place the glider bag over the glider and then turn the glider on its back. 

12. Dismantle the 'A' frame.  Attach the 'A' frame padding which is located around the bottom of upright 
castings. When packed the side wires should come smoothly out of the top of the packing.
 
13. Put the speed bar into its bag and store in the sail near the wing tip. Any remaining ties should be put 
around the glider. Tuck the nose cone under the tie near the nose of the glider.

14. Zip the bag up and store the glider dry in a cool dry dark place.

VB. (VARIABLE BILLOW)

The variable billow (VB. sometimes called variable geometry VG.) is used to change the flying 
characteristics of the glider while in flight.

As mentioned else where in this hand book, when the glider is rigged the VB. cord should be threaded 
through the cleat on the speed bar and knotted. (This is a good habit to get into. The knot will prevent the 
end of the VB. cord being lost.)

If anything is attached to the right hand upright (the one down which the VB. cord runs) it could adversely 
effect the operation of the VB. (See 'trouble shooting'.)

For take off it is recommended that the VB. is in the fully released position. (This is with very little cord 
sticking from the upright.) In this position the glider is easiest to turn. (You may find with experience, and 
especially if aero-towing, that you prefer to take off with a little VB. pulled on.)

In normal flight a little VB. (Say 70cm of cord) might be pulled on. This will give a better sink rate with 
little loss of handling.

For flying fast or for best glide performance (for example, flying between thermals) use full VB. With full 
VB. be aware that the roll rate of the glider is significantly reduced especially if flying slowly. 

Do not use 

full VB.

 near the ground, near other aircraft or near any other obstacle.

For flying near the ground, other aircraft, other obstacles, in rough air or landing it is recommended that 
the VB. is in the fully released position. This position will give the most effective roll control.

Release the VB. in a smooth manner. Do not just pull the rope out of the cleat and let go. This will give a 
needless shock loading to the airframe.
