My Mini Nimbus creaks on hot days -- more if it's been left out in the sun

before launch. It sounds like flexing plastic to me, and I've always put it

down to the canopy expanding/contracting a different amount to the fus. I
think it goes away eventually in flight (or at least, I tend to only notice
it at
first).

Your video sounds more like a banging noise, but it's hard to tell from the

video... it could be the same creaking perspex noise I hear.

Gliders with removable lift pins have the shims under the shoulder of the
pin.
