I'm typed in this very same aircraft. As a Challenger 605 pilot and sim enthusiast this is more than you can expect for a sim model. It is as good as it gets. Most of us don't get to experience and compare what we fly in the sim and the real airplanes we would like to fly, but this is the real deal in terms of aircraft systems, sequences and internal logics (engine start, APU bleed transfer, fuel xfer), Collins pro line 21 adv. 6200 with all working functions, I mean, this is worth the effort and the price. Absolutely recommended.
