With so many other Blackhawks made for FSX, I was a bit skeptical about getting this one. But in true CeraSim style, this is by far the BEST Blackhawk for FSX. The model is great, the details are great, the sound is very good, and the performance is great. It does not hog up the FPS too bad. Im getting 35 to 40 fps on max setting with it on a Dell Inspiron 17R laptop. I will say that the pitch / yaw / roll rate is a bit on the slow side. Even after removing all payload weight and giving it only 25% fuel load, it still handles a bit slow and sluggish. Speed is also a factor, it will do 345 knots in a dive which is totally un - realistic. I was hoping for retreating blade stall around the 175 to 180 knot mark. But it just flies right through it. One thing that is great is the lights. They are bright and vivid, and stay on from any angle unlike most other lights due to the DX10 ballast glitch. All in all, I would definitely give it 4 out of 5 stars. Perhaps a re-worked AIR file with better flight characteristics in a future update would be nice.
