Why does my Alphasim B-47 fly in such a nose-heavy attitude? I have to offload all the fuel to make it look right, and that's not very realistic. I'm looking through the .cfg file and it appears that nothing is equal or balanced

[fuel]

//Longitudinal (feet), Lateral (feet), Vertical (feet), Usable(gallons), Unusable (gallons)

fuel_type = 2
number_of_tank_selectors = 1
electric_pump = 1

Center1 = 8.000, 0.000, 0.000, 2954.000, 24.000
Center2 = 0.000, 0.000, 0.000, 2874.000, 64.000
Center3 = -6.000, 0.000, 0.000, 3445.000, 15.000
LeftAux = 4.000, 0.000, 0.000, 1050.000, 0.000
LeftTip = 8.000, 0.000, -1.000, 1170.000, 30.000
RightAux = -3.000, 0.000, 0.000, 1260.000, 0.000
RightTip = -6.000, 0.000, -1.000, 2370.000, 0.000
External1 = 0.000, -10.000, 0.000, 1695.000, 5.000
External2 = 0.000, 10.000, 0.000, 1695.000, 5.000

None of the aux or tip numbers match either and you'd think the left and right sides would be equal. Does anyone have a fix or correct numbers to make it right?

Are you experiencing this nose low attitude at low level and high speeds only or at high altitudes as well. Remember the role the B-47 was designed for. High Speed and High Altitude long range bombing runs on the former Soviet Union. Later Recce versions were added but the mission profile did not change significantly.

As such the wing on the B-47 may actually produce too much lift in the much denser low altitude air and such a nose low attitude may be quite accurate.

You will see the same effect on my beloved four engined prop liners when you keep the throttles pushed up down low. There is nothing wrong with the FDE in those cases either....just bad technique.

Its natural at low altitudes........use positive trim, should help a bit to keep her level

Remember the B-47 was designed to bomb from high level. When she was deployed, she was designed to bomb from an altitude of 40,000+ ft ASL. Try making a run at high altitude at about 60% thrust, i bet you get a good run from her
