Multi-rotor rotorcraft (10) comprise a fuselage (12), and at least four rotor assemblies (14) operatively supported by and spaced-around the fuselage (12). Each of the at least four rotor assemblies (14) defines a spin volume (24) and a spin diameter (26). Some multi-rotor rotorcraft (10) further comprise at least one rotor guard (50) that is fixed relative to the fuselage (12), that borders the spin volume (24) of at least one of the at least four rotor assemblies (14), and that is configured to provide a visual indication of the spin volume (24) of the at least one of the at least four rotor assemblies (14). Various configurations of rotor guards (50) are disclosed.
