Plane problem with evalon 1.4.3

[Cassel]

When I pull up my planes does

 

when I am trying to pull down

It should work like that? Wings are attached to this middle part with intake, I have installed BD armory.

The elevons take into consideration your CoM (Center of Mass) to determine which way they should deploy... The back fin is behind your CoM, while the elevons on the wings are in front of your CoM, hence deploying in the opposite direction, although they "seem" to be almost aligned with your CoM, so they may be doing little to no effect in pitching up/down

Yeah. What they said. 

Change the authority limiter in tweakables to a negative value to make it go the other way.

[Xd the great]

Highly normal. As long as your plane turns the way it should, it is fine. If not, tweak with the settings.

What you are describing is exactly how elevons should work 

Perhaps taking a look at the following link would help you understand the why of it working this way
