Query: Parsec Scale Properties of Radio Sources   We present a new complete sample of radio sources selected from the B2 and
3CR catalogues, with no bias respect to the jet velocity and orientation. Using
preliminary data we investigate the parsec scale properties of radio sources
with different radio power and kpc scale morphology. We stress the evidence for
high velocity pc scale jets in all sources and conclude that the properties of
parsec scale jets are similar regardless of the source total power and large
scale morphology. Moreover we show two epoch images of two nearby radio
galaxies: a low power compact source and a CSO. The comparison of the two epoch
images suggests that in both sources the size is increasing with time. We
derive a possible advance speed and estimate their dynamic age.
