Showing Rush tossing the controller while saying "it's bluetooth so I can hand it to anybody... it's meant for a 16 year old to throw it around and super durable" is powerful imagery for a jury.
The complaint specifically mentions Bluetooth, which I can't tell if it's an error. They switched from the DualShock controller used in Cyclops I, which does use Bluetooth. There is probably a reason they switched wireless technologies (Bluetooth is even worse than Logitech's 2.4 GHz wireless), which if not documented, could also show negligence.
Your carbon fiber hull fatigue theory is interesting.
I picture it sitting out in the hot sun and cold nights for months. It reminds me of the CNA building in Chicago, where windows fractured due to uneven sun exposure. The owners didn't replace them until one fell and killed a pedestrian, resulting in an $18 million settlement in 1975.
