Thread: No lpg bottles on choppers

LPG is a mix of propane and butane, its relatively a low pressure containment gas and the average container should not be an issue unless you get to extreme high altitude (way higher than a chopper) where atmospheric pressure is so low the vessel may rupture.
the main issue is that if a bottle does leak it tends to "sit" in confined spaces unlike natural gas which is lighter and expands to fill the volume.
so if you tied your bottle to the heli's skids you have eliminated that risk
