I'm not quite sure it's the same thing, but I many years ago had an idea for inflatable control surfaces for low-speed vehicles place of mechanical ailerons. I was in between jobs at the time and thought it might be an interesting diversion, especialyl as I've always been a bit of a plane geek. I'm sure it might've been, but after buying a few books on patenting and general design development I quickly realised I was going to be in way over my head and that my savings - grand as I thought they were at the time - would barely make a dent in development costs. Ho hum.
