Adding Electrical parts like electrical engines and solar panels/batteries and different tiers of electrical engines batteries and solar panels. Adding solar wings and wings that gain electrical input from forward motion like kinetic generators. (of course, the solar wings would be resizeable) Anyways I would also love to see a physical seat and walls around the cockpits available. Each cockpit would have an interior that summarizes the period its from. (default one would be 2002 to 2009 and sleek one would be 2010 to 2020).
