Hi everyone: I just wanted to let You know that I got My atlas GP9 gold series a few days ago and I just tryed it out today. It runs great.It has all the features you could think of air let off dynamic break cooling fans just to much to list, crawls like its just plain lazy,all on command. It's also noisey just like a real eng. I forgot to mention momentem.It's quite a engine. .........Booyak.........
