4137 x 67.8 = moment of 280488.6

You've burned off a moment of (13.7 * 1.5 * 6 * 68) = 8384.4 and 123.3lbs of weight

280488.6 - 8384.4
----------------------
4137 - 123.3

It doesn't really move. Had I read it closer the first time I would have seen that the fuel is basically getting burned right off the CG (more or less), so fuel burn won't (hardly) affect the CG

Hello

sorry for the silly question how did you get the 1.5 and 123.3

 

[EdFred]

1 hour and 30 minutes is 1.5 hours
13.7gal/hr * 1.5 hr = 20.55 gallons

20.55gallons * 6lbs/gallon = 123.3lbs
