to all, make no mistake, you can get VERY messed up by inflating floats. trust me on this as i have personally installed many "first article" installs for apical, test inflations and test flights and have blown myself clear across the hanger, fortunetly i hit nothing solid.
my office is in there building and around here we take float inflation testing with extreme caution. be very careful around floats and always check the tension of the float bottle straps, cable slack (if mechanical) and binding on the release mechanism. in the shop, PIN the bottles, everytime!
btw, packing floats sucks
