Max, I love you use of those airbags in your elevator. I am planning on creating a virtual ride (similar to Disney Star Tours) for my next haunt using airbags and I was wondering if you could tell me a bit more about how you interface your compressor/reservoir setup to the airbags. What are the connections to the airbags? I assume solenoids for air control are separate from the bags? Do you have pics of how you hooked up? In one of the videos on the thread where you posted your elevator pics/vid, someone mentions the need to add heavy chains to prevent the bags from overinflating, but I didn't see anything like that on your elevator setup. Did you have to deal with overinflating? Finally, any other advice you could offer?
