HUGEWEATHER BALLOON (meteorological sounding balloon) ML-541A/AM.
Manufactured by Kaysam Industries in 1982. This balloon is military surplus, balloon weighs about 5 pounds.
This balloon CAN be inflated to 10 to 12 foot in diameter, however they start to look pretty good at about 5 foot in diameter and will fly nicely at about 7 foot in diameter.
How much can this balloon lift? With Hydrogen when inflated to about 7-1/2 feet in diameter and it had almost 7 pounds of lift. The less gas you can use the higher it will fly. I think about 2 pounds of free lift is about right.Best offer,or trade.
