Abstract
In a small sample of extragalactic radio sources, curvature is found to be a common feature in bright radio components coincident with quasi-stellar objects. In 3C273 and 3C345 the curvature is smooth between the nuclear (<0.003″) and the outer (>1″) regions. This contrasts sharply with objects having comparatively faint central radio components, which are often well aligned with the extended features.
