We analyse the jet-to-counterjet flux ratios measured from deep VLA images of 13 3CR quasars made by Bridle et al., in order to derive constraints on the degree of Doppler boosting (and hence the characteristic jet speeds on kiloparsec scales) and on how much intrinsic asymmetry between jets and counterjets is permitted. The main result is that the large jet-counterjet brightness ratios measured b...
