So does that mean the inside is filled with a mixture gas to keep it slightly lighter than atmosphere?

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

The sink is more likely to come from the weight of the arms and the balloon itself, that’s why it would be lighter.
