Hello,

I am hoping someone with balloon mapping experience can answer my question or direct me to a resource to identify the correct size tank need for 1 flight. Of course, I will want to have more than one flight, but I am trying to get the minimum specs down for now.

I ordered and received a 5.5 foot (170cm) reusable* balloon made of a latex/chloroprene (neoprene) mix which is a part of the Balloon Mapping Kit. Would 14.9 cubic feet of helium tank that is 80% helium, 20% air blend work for filling this up at least one time?

Thanks,

Derek
