Why does one set of elevators/ailerons deploy opposite than the other two sets?

[What Zitt Tooya]

I installed three sets of these control surfaces on my poor excuse of a STS. For some reason, one set (the inner sets) deploy opposite of the other two sets. This is a huge problem because I can't get lift if one set wants to push me towards the ground.

In the SPH I've tried rotating them and tried having them deploy inverted. For some reason they still want to deploy in that direction.

Am I doing something wrong?

Edit: Setting the Authority Limiter to -100 seems to fix it, but why?

Note: I'm still a noob at designing aircraft, especially this behemoth

This is the weird thing with how control axis are determined. The two on the angled part of the wing likely align in front of CoM while the one mounted perpendicular aligns behind it.

Edit: Or it might be the other way round and the perpendicular aileron sits in front of CoM.

Another edit: really, you shouldn't use wing mounted ailerons for pitch. Mount something at the tail for pitch authority and only use wing mounted for roll.

hmm interesting, thanks
