Indeed it is, and my comment should be read in the context of the post I am replying to. Having wings gives Heaviside an advantage over purely multi-rotor aircraft most of the time, but during VTOL operations, there is a stage where the wings do not help.
Helicopters have an advantage over all other VTOL aircraft in that they can autorotate, though this is especially tricky in lightweight helicopters, on account of a lack of rotor inertia.
