  The most general local, classically scale invariant, perturbatively
renormalizable, globally $SU(N)$ invariant Lagrangian is constructed for spin-1
fields in 4 dimensions. The total number of independent couplings is 7 and the
1-loop $\beta$-functions are computed in the MSbar scheme. A number of
asymptotically free RG flows are identified corresponding to non-trivial QFTs.
None of these are gauge theories. The details of the large-$N$ limit are also
worked out and it is shown that the RG phase space is qualitatively similar for
all $N>5$ including the $N\to\infty$ limit.
