Canopy material
Stupid question I've had for awhile and haven't come across the answer. Why do BASE canopies still use F-111? I see that some use zp in the nose of the top skin to help lift and flair but why not use it for the whole thing? Correct me if I'm wrong but zp inflates quicker and lasts a whole lot longer. The downsides I see are cost (which I doubt is the key factor here) and difficulty packing. anything else? did a few searches and couldn't find anything. Just hoping for some more info. thanks!
