Experienced racers have long known about the dreaded sag.


I know this reply was in jest but at Hobbs years ago I got into
conversation with a DG owner. I forget who it was or what the glider
type was. He told me that the gell coat on his wings had sagged. He
also told me the factory had told him it was due to being stored in
the trailer above a maximum temperature approved by the factory. He
seemed upset enough about the problem that I assumed it was true. I
have never heard of this happening to anyone else and don't pretend
to understand the physics that could allow it to happen.
