Since I bought and installed AES I am having sever problems with at least two Add-on aircraft. My idea was to use AES as weather engines with Direct Weather Injection and REX overdrive for the texture. The weather engine in REX is disabled. I am flying with FSX and online on VATSIM with FSInn. Weather update in FSInn is disabled.Shortly after beginning to taxi the aircrafts stops suddenly. To get the aircraft moving again I need at least 70% N1. On takeoff the acceleration is very slowly and I need the longest runway available. With some luck I am reaching Vr before the runway ends. In-flight, flying with auto throttle the Aircraft is sometimes accelerating into over speed and keeps accelerating. This behavior I have with the iFly NGX. With the Embraer 175/195 from feelthere I tested just the taxiing issue.After several test flights I can say that this has something to do with the AES. Before I used the Weather Engine from REX and never had any problems. I also deleted the FSUIPC.ini and started with a new one. The settings for FSUIPC and FSX are as described in the documentation. I am a bit frustrated and removed AES for the moment. Any help would be very much appreciated.Felix
