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.)
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 .
