We have explored the behaviour of some improved actions based on a nonperturbative renormalization group (RG) analysis in coupling space. We calculate the RG flow in two-coupling space $(\boneone,\bonetwo)$ and examine the restoration of rotational invariance and the scaling of physical quantities $(T_c/\sqrt{\sigma})$.
