Then the cone angle drops, and raises again, before the rotor drops a lot around 10 seconds, one frame seems like blades are crowded in the front, spreads out flat again and one blade departs.
Except for the blade departure, clear in a 0.25x reproduction, I really need to check my glasses or get a bigger screen.
