🚨 THIS IS A FALCON 9 LANDING TEST - IN A LIVING ROOM.
What you're watching is a custom EDF rocket. No propellant - a 90mm ducted fan inside a duct pushes mass downward, same physics as a rocket engine, just electric.
70mm fan on 7S makes 8kg+ thrust - thrust > weight = hover. Uses thrust-vectoring + PID like a real lunar lander.
