There is mounting evidence that mechanical radio-mode AGN feedback is important in galaxy evolution, and in order to quantify this feedback, detailed models of radio lobe evolution are required. Self-similar analytic models exist for large FRII radio sources but the evolution of the young precursor radio sources is not yet fully understood.

This talk will present a dynamical and radiative model for young source evolution (sub-kpc scales) as an extension to existing self-similar models, and discuss the full model in the context of a sample of nearly 100 radio-loud sources. Robust knowledge of the host galaxy properties of this sample allow certain evolutionary tracks to be observationally ruled out in a new method of tracking radio source evolution.
