POSKY 747-400 problems

[beaky]

Trying to fly this model "by the book", but the manuals included are for the -100 and -200 models. The gross weight of the -400 is well over that of the -200, according to the model's F&P specs. That weight is way off the -200 chart...
 I suspect this is why I can't seem to get it to level off at the altitude I've programmed into the AP... even with Autothrottle on and the book-spec Mach #, she overspeeds immediately, and can't be recovered.
Another question is: if an altitude is programmed, and an airspeed, how do you determine the best rate of climb? None of the charts in the manual show a target rate of climb.
I guess I could go by the little information provided in the default -400 specs...?

 ;D Maybe it's too  aerodynamic , there's a said among pilots that the 747 does, but this its funny exagerated  , this its weird  ::)

LOL- but I know it can be flown; I see that Virgin 747-400 out my window on a regular basis, climbing out on its way to London. I can't understand why they'd include manuals for the -100 and -200 models if the FS model is a -400 (or IS it?)...
 I just need to find out the correct IAS/ Mach for climb above 10, 000 ft., plus a ballpark rate of climb. May have to try to find the manual for the real thing...
