Probably would work once or twice, and then some kid will notice copper foil tape makes great Faraday shields. Hams already do this cage technique all the time to help lower the noise floor on cheap equipment.

Probably better off with #12 or #9 bird shot shells, or a cool pet falcon named Xavier. =3

Anything with a power supply and a radio receiver has some susceptibility.

No radio on fiber drones, but anything electronic is effected. Truly effective shielding gets heavy, and cuts the payload and range significantly.

They actually do still have a radio, it's just not critical to the mission.

yes because it attacks the coils in the motors.
