A deep radio image of the microquasar GRS 1758-258 has evidenced for the first time a new link with the so called `winged' radio galaxies. This opens a new perspective for the understanding of these secondary lobe features in relativistic jets. The fact that we also find them in a relativistic stellar outflow is better understood in the context of hydrodynamic models. This is in contrast to other alternative interpretations that are mostly based on the spin-flip of the central black hole in radio galaxies.
