I very much doubt the machine we saw flying was 1000kg+. It was either MUCH lighter, supported by cleverly hidden cables, or some other trickery. The dramatic lighting isn't just for visual effect, it makes it easier to hide the reality of the demonstration.
If there was a live audience anywhere near that stage they wouldn't have been able to use thrusters to fly something that actually weighs as much as a car.
