New Posky 747-100/200 V4

I just tried the V4 Posky 747 classic. I'm somewhat disappointed. I flew the NW old color version. I have loved Posky aircraft but since the last version of the 767 the air files have been not to my liking. I'm not going to say unrealistic because I'm not a 767 or a 747 pilot. I have RFP to compare too. The engine fan texture is very poor. The ground steering is aweful. At one point I was drifting sideways which was very odd. At 10 knt on the ground it is difficult to steer and the rear wheels do not track the front. The strobes look vintage fs2000 compared too other freeware. I'm going to tweak some to fix to my liking. It seems if the previous version was better but again I merged the RFP panel with the previous version.What do you think?
