Better Engine mounts

[Jack5.exe]

I was making a rocket with 2 engines for a stage and I couldn't because the bi-couplers only have the 2 engines nodes so it won't be centered, is there any mod for this?

I would just use cubic struts as mounting points. It might not look the best but it works.

The answer to all things: Struts!  (I'm assuming this is the configuration you're trying for)

Only one of those engines is attached.  The other decoupler is just for looks, but the struts are enough to keep it stable.  This particular rocket got to orbit just fine.  However... this is not the way to do this.  Best option is a better engine.  Or, if you must, attach them "radially" like @Jas0n was getting at.

It would be really helpful if you would post a screenshot of what you have.  It's nearly impossible to help with any problem in this game without seeing what you already have.

Put a bicoupler upside down below the engines

I know some mods have reasonably effective interstage adapter plates which have multiple engine nodes and a "floating" bottom node.

SpaceY (and SpaceY extended)

Also notable is Procedural Parts, which has a scalable thrust plate with a center and an adjustable number of additional points in a circle, and the procedural interstage fairing from Procedural Fairings. You can attach the procedural fairing's upper node to the center node of the thrust plate (or your center engine), and put engines on the outer points.

@Jack5.exeJust place them on Cubic Octagonal Struts, and attach a truss with a decoupler in between. Then, put a fairing on the interstage and strut it well.
