Owner`s Manual
11. Place the glider bag over the glider and then turn the glider on its back.
12. Dismantle the 'A' frame. Make sure that the packing 'wings' are alongside the
top of the uprights. Check that the spreader bar attached to the hang loop is not
caught between the uprights. Connect the ends of the uprights with the spacer
provided. The side wire can then be threaded though the 'A' frame padding which is
located around the bottom of upright castings. When packed the side wires should
loop out of the bottom of this padding so that they are not kinked.
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.
POST FLIGHT INSPECTION
After landing, especially if heavily, the glider should be inspected as outlined in the
pre-flight inspection.
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.)
The VB should only be operated when the glider is standing fully rigged on its A
frame. Operating the VB. while the glider is partially rigged or rigged flat might
cause it to jam or damage the airframe. If the glider is rigged flat and the VB. is
pulled on the side wires will become very tight. This puts very high loads on the
airframe. (The area most likely to give is the speed bar to stretch.)
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.
