Have to draw a line under the construction phase and this is it, with the battery-packs arranged on the flight deck and situated beneath the seat (whose locator lugs and tie-downs can be seen around the periphery). For flexibility during flight-testing the inner packs can be removed if the flight control computer is to be fixed top-side, or with it fitted underside the inner packs or all four can be used. But I need closure, and this forms the basis of a practical air vehicle, if only for flight in ground-effect in the first instance.
