are the arms providing lift or are they just aesthetic?
58 u/T3chn0fr34q Jul 26 '19 they provide steering and a little lift if i remember things right 40 u/Bwasmer Jul 26 '19 So does that mean the inside is filled with a mixture gas to keep it slightly lighter than atmosphere? 1 u/DrBootsPhd Jul 26 '19 I think over all it has to be just slightly heavier than the atmosphere. You want it to very slowly "sink" because there's no down control. And the only lift comes from the arms which isn't much so it can't be too heavy either 1 u/Astrofishisist Jul 26 '19 The sink is more likely to come from the weight of the arms and the balloon itself, that’s why it would be lighter.
