Hi Markoz.
I have submitted a ticket over this,i have also been fine tuneing my aircraft.cfg file.
I could never get the nose level , no matter what i did , the nose always ended up 5 deg nose up,if it is 10 deg nose up , then in cruise with auto pilot on , the aircraft was rocking , as as been reported in these forums , but when in cruise with auto pilot on with the 5 deg nose up , she was steady as a rock.
Then i did some changes in the auto pilot section of the cfg file, i was over the moon , when i got the 0 deg nose up attitude in cruise,but it did not last long,i have found that the problem is down to Microsofts default fuel usage.
The tanks where selected as per a post on this forum,which i copyied into notepad,and had that on display, engs 1,2 fed from aft, engs 3,4 fed from its main,engs 5,6 fed from its main,engs 7,8 fed from ctr wing tank , this was done till i started climbing,then switched to engs 1,2,3,4 fed from aft,engs 5,6,7,8 fed from ctr wing,when i looked in Microsofts fuel , i found fuel was being drained from tanks that where not even selected , this means that the aircraft cannot be ballanced correctly.
Only way to get this aircraft to use fuel in the correct way,would be for captainsim to modify the ACE , so it worked a bit like the C130, I.E. weapons load page,fuel load page, this is the only way to get around FSX limitations.
