Never store the KA-UG L+R in their carrier (that is used to bundle them so one can put them onto the Kapex) in upright position. At least not in a not climate controlled environment: I just noticed that mine managed to condensate enough that the bottom plastic part of the strap-carry-contraption was completely filled with water.
The wings seems to have enough thermal inertia (and a large surface to make them effective) that the best way for them to increase in temperature seems to be turning water vapor into fluid - the rooms my shop is located in currently have some heating problems (which isn't that fun at -12°C outside) which lead to the temperature dropping ~10°C repeatedly (for several hours each) the last 1-2 weeks. I checked everything and havn't found puddles of water somewhere else (tools in systainers are fine etc), only the wings went 'land under' - and no, the water didn't came through the ceiling.
So in case someone else stores the wings in changing climate conditions and upright, like strapped to the wall in a van or (as I did) leaned into the corner somewhere: it might be a good idea to take a little drill to create water drain holes at the then-bottoms of the strap holders.
