I believe I am but I might be wrong.  Basically I flew it for a few hours straight to see what tanks it was drawing from first.  It always drained from Externals 1-2, R-L Tips and Center 3 first.  So I set all those at 10%(except Center 3), to see what it would draw from next.  But alas the engines would end up dying out shortly after takeoff.  The only thing that seems to work is to bring everything down to 60% and on a 1600nm flight I had no issues.  Also again in "Fuel and Payload" it says I'm 20,832 over gross weight.  Does anyone else have this?  Again thanks for any info here.
