Whatever else you do, if strongs winds are possible
then securely tie down (not weigh down) the wing tips
if they are sitting on unstable tripod stands.

In a serious wind, if the glider is facing into wind
then the wings can fly and bend up away from the stands
which then fall over and the wings then can bang up
and down on the fallen stands - which, in the case
of Cobra types, have sharp pointy bits that stick up
when the little legs are folded.

We had this happen to a Duo a few years ago - the wings
tips were weighed down by being tied to 25kg water
bottles which just lifted with the wing tip. The same
day an ASH 25 had its wings lifted and its stands blow
over but it then blew backwards 10 yards so the tips
land on grass and not the stands.

I now chock the wheel front and back, use stable old
fashioned wooden wing trestles and tie down the tips
with sleeves attached to 'The Claw'
