Though the Stemme S10 did not originally come equipped with a rear canopy leash for it's double wide wind sail canopy, most owners quickly add them to prevent the otherwise almost certain hinge damage.

I *always* removed the canopy attach end of mine before flight. To make this step go easier, I threaded the end of the cord through a short length of flexible tubing and then tied the cord end back around to make the tubing into a snug loop on the rear canopy handle.

Better to have the canopy go away clean than than take the risk.
