Center of Lift confusion

[Sirrobert]

First of all: This is in NEAR, so not stock aerodynamics. I'm asuming this is relavent.

Ok so I have stumbled upon a very confusing aerodynamical oddity. My rocket, which is perfectly symetrical and ballanced CoT, has an offballance Center of Lift.

Since I REALLY do not understand aerodynamics, I was hoping someone could explain.

Pictures:

Build with 3 way symetry, the craft is perfectly ballanced without the wings, but offballance WITH the wings. The wings, which are symetrically placed, somehow throw the thing offballance

Drag.

You don't have nosecones on those outer tanks. Because of the way air spoils around bodies like that, I would suggest the lower, outer tanks be attached to the lander with stack decouplers and then strutted to the main body. That way you only need 3 nosecones instead of 6.

But that it's fine without the wings, and without nosecones

No, it's not. It just doesn't show lift without a lifting surface. The blue ball is completely meaningless without wings. (Really the blue ball is meaningless all together in this case, that little bit off center isn't going to mean much, but if your craft is hard to control, it's drag)

I see. I gues that's what I was missing than. Thank you.

This is why I was suggesting bringing the upper and lower tanks together. Same basic principle. I do not know if NEAR replicates that drag in the back, I would think it does.
