An RSRG approach to the Witten-Sander directed DLA model is presented. The authors get the extrapolation value V/sub ///<sup>ex</sup>=0.525 and V<sub>perpendicular to </sub>=0.555 by 2*2 cell-site transformation. It is confirmed that directed DLA and directed animals are in different universality classes.
