So we just purchased a 6 air bag kit from Fright Props - our intention is to make a 16 foot bridge drop about 5-6 inches that will be triggered when our guests reach the middle - the bridge will only be about 10 inches off the ground. We plan to use a hinged ramp system to avoid and pinch points that the raising and lowering will cause. I have never used air bags and wanted to know if there was anything I should be aware of? I know I need to limit the lift so they don't over extend - if there anything beyond that I should know.

Thanks for any pointers!
