Some highlights from the video:
They have decided to move all manufacturing and testing to Punta Indio, with a simple HIF at Puerto Belgrano.
They will use structural tanks with friction stir welding for the Tronador II fuselage.
The engine test benches will also be housed in Punta Indio.
They will have two sites, actually. One for the test launches of the VEX, and another for the factory.
They will develop their own composite pressure vessels (400Bar) for the pressurizers. Also development of spherical tanks.
