Adjust the elast strings 
The purpose of the elastic string is to maintain the cover in the right position in windy conditions. 
- Tie the cover underneath the body using the elastic string and the plastic hooks. 
- On some plane types, it may be necessary to cross the loops and hooks underneath the wing. 
- Adjust the tension on the cover by moving the knot at the hook end of the elastic string. The tension should be light. Once fitted, tighten the knot and cut away the excess string at least 1 centimetre from the knot and burn the end lightly.

Making holes for Pitot Tube and tie downs, etc.  
- Find the exact place for the hole.
- Cut the patch of stick-on material to size so that it is at least 3 centimetres bigger than the hole you need to make - all the way round the hole.
- Make sure that any corners are rounded off.
- Peel off the protection paper.
- Place, and stick on, the patch where the hole needs to be.
- Place a piece of cotton / linen material over the patch and iron with a fairly hot iron (not quite as hot as for cotton) for approx. 10 seconds.
- Cut the hole to size preferably using a sharp scalpel 

Wing covers suitable for shorter tips 
Fold the ends into the cover underneath the wing, when they using the shorter tips. A Quick and cheap solution!

Repair of tears - Using stick-on material
Cut a piece of the repair material (stick-on material/self-adhesive cloth), big enough to cover the tear – approx. 3 centimetres at all sides – and round all the corners before removing the paper and sticking it on. Having placed it very accurately you cover it with a linen cloth - a tea towel for instance - and press it with a hot iron (not quite as hot as for cotton) for approx. 10 seconds.

Making ther covers fit round probes, aerials and antennas 
As probes, aerials and antennas mostly vary in type and placement, we need some photos or a sketch on which you mark in centimetres all distances for these relative to the edge of the windscreen.  We must state that only if we get these specification from you will we be able to make the covers fit round the probes and aerials. Of course if you find it easier to have it made locally we will send all necessary material.

Making design for special tips / winglets
Make a pattern. Place a piece of paper or plastic on the upper side of the winglets and draw a line along the edge. The pattern will give us the correct angle and size. The best is if the pattern is as big as the complete winglet so that we can make the joint in the right place.

Measuring window for solar panel
Inform size and the distance following the glider’s shape along the centreline from the front of the nose to where the solar panel starts.
