Im planing to Payload 1000g to Hwoyee HY-1200 balloon. But I have some questions before it.
How much helium does it take to fill the Hwoyee HY-1200 balloon?
Do I need to buy a parachute or is it included to Hwoyee HY-1200 ballon? If its not included what sized parachute do I need to buy?
Thanks a lot for great answer I hope you gonna save my day guys...
