Michael, Alex: Everything is done on bare-metal necessitating an inetrrupt-based approach. There are no off the shelf operating systems running on the ARM9.
James: The front white piece is not the fuel tank. It's a protective foam block which also includes the batteries and any counterweight required for establishing neutral stability. The fuel is contained within two bladders on the CG. In the illustration, they are the two rectangular objects at either side of the middle section.
