Okay, I packed the thing with intakes, and the engines will run without flameing out. It will appearantly run on no less than three wide intakes and five narrow intakes, which sounds wrong to me.
Now, the plane is imbalanced for no reason. It's not my piloting skills, for as soon as I take off, it gravitates towards the right. I checked the engines' readouts, and they're outputting equal amounts of kN, so it has to be a weight issue. However, the CoW/L indicators in the AB look fine.
