I was thinking this 747 flies like sh-t. The flight dynamics aren't realistic at all. The FMC doesn't work nor do alot of the dials. For example I was flying a flight last night from KDFW to KATL and my speed thing was acting up. At one point it was saying I was flying at 275 KIAS and then a second later I'm flying at 365 KIAS. I ended up getting an overspeed warning. Also the autopilot speed mode doesn't work all the time, mostly when I descending from cruise. Like I'll set it up for 250 KIAS with autothrottle on for descent but the lowest I'll get to would be 275 - 300 KIAS. That screws up my approach and landing. Also a couple of times I took off at full weight and soon as I would reach about 20,000 feet I would stall out and crash. As soon as I get the money I'm going to get PMDG 747. Its probably 100 times better than the default one.
