Re: Consequences
The tests for aircraft engines typically involve firing a frozen chicken into the intake.
The engine WILL be destroyed. The tests are intended to check that the resulting debris doesn't make it out sideways from the engine and so penetrate the cabin. A quadcopter strike would be similar in mass to a bird strike.
A pilot will be left with a hugely unbalanced aircraft, and so an immense workload right at the point when the normal workload is highest - at take off or landing.
A bird striking other parts of the airframe has serious consequences too. Hitting anything solid at a couple of hundred miles an hour is bound to cause havoc to the lightweight materials used.
