Project Opensky released the first of many liveries that adorn their new CRJ-900 version 3 model for flight simulator. I will save you the hastle of having to read a lot before you get to the download link and I will just post the link to the download. As for flight simulator version compatibility, it was designed for FS9, but would likely work in FSX as their CRJ-700 does.
I took this beauty on a short flight from Heathrow to Prague to get a feel for its FDE and another look at the exterior model. You know, POSKY surely knows how to model the CRJ. Their CRJ-700 model set a new standard for animation and eye candy. It is no surprise that this new CRJ-900 model shares the same new standard. Very cool stuff.
The FDE is behaved with only a few surprises. The throttle response seems slow to pickup, but when it does, hang on. I found myself constantly adjusting the throttle to maintain speed both while taxiing and during flight. I believe this is a characteristic of the real world CRJ. Nothing to complain about, but it will take you surprise the first time you experience it.
2/2/10 – note: A bunch more liveries are now available in the download site. Liveries now include: Adria, SAS, Delta Connection Multi-Pack, and SkyWest 35th Anniversary edition livery. Go get em!
