The BBS A330 does the job more or less just not at what its priced at. Many of the switches don't work like the IRS for example, but the systems are mostly modeled realistically. Its better then the CLS A330 because there are realistic systems in it. BBS A330 is also better than Wilco because there are less bugs and there is a much better exterior model. This aircraft is the best a330 on the market, it's just over priced because it's not a complete plane yet.
