# High-speed Steady Flight in Confined Spaces for Tethered Quadrocopters

High-g quadrocopter training in the Flying Machine Arena at ETH Zurich.

The testbed allows the characterization of the flight behavior of quadrocopters at high airspeeds, identifying for example drag characteristics and propeller efficiency. Furthermore, the physical limits of the machine can be identified. The testbed can also be used to safely develop high-speed maneuvers, such as emergency braking.
