question about attach engines

[Grek]

Hello, guys, i tried to attach engine with this method, but after staging they separate and 2nd stage continue to fly on 1 engine instead of 4. is there is a way to attach engines properly?

The important thing to keep in mind is that (in general), rockets in KSP are trees and don't allow for loops. This means that 1->many->1 setups like you have their are fraught with problems, and you'll need some sort of workaround

Not that I generally endorse this sort of thing, but instead of trying to attach four 1.25 decouplers, each to an engine, just have the adapter as you do and put the Rockomax decoupler under it. The engines should destroy it just fine.

This was useful. Thank you, comÑÂade

I'm pretty sure if you attach docking ports to the bottom of your engines, and attach them in the same location on the next stage, you can make something like that work. On launch all the ports should connect, it's not going to be easy to build though.

Here's another method that's maybe a little neater, using docking ports http://forum.kerbalspaceprogram.com/threads/43621-How-to-have-engine-clusters-in-upper-stages

You'll want to put some struts around there though since the docking ports aren't as rigid as decouplers.
