add Helium Cells
It works like a fuselage where you can afjust the size, fuel, and dead weight. But you can also add the amount of helium gas in the cells. The larger the amount of gas, the more likely it is to float. We can use this to make airships and air balloons. Im sorry if I stole this idea from others. The idea just came into my mind
