We reexamine the problem of delocalization of two-dimensional electrons in the presence of random magnetic field. By introducing spatial correlations among random fluxes, a well-defined metal-insulator transition characterized by a two-branch scaling of conductance has been demonstrated numerically. Critical conductance is found non-universal with a value around $e^2/h$. Interesting connections of this system with the recently observed B=0 two-dimensional metallic phase (Kravchenko et al., Phys…
