Mostly the 4x4x2, 3x2x1, and 5x6x1 400mm LW armor blocks for the ship, and a few 24x10x2 blocks for the base. As for your second question, Firefly starts at 4000m (I think) and rises to 4800, and Overwatch starts at 4900m (base 25m underwater) and stays level (propellers pull downward, but I just got really lucky with the weight balancing so it maintains 4900m altitude always).
