lol the 2-man concept looks a little... cozy.

Well I could be wrong and lucky, but I found it workable (single stack to multiple fuel tank with adapter, back to single engine with inverted adapter) when I flip the adapter over... AND remove the symmetry (shift-X) before placing it upside down on the bottom of the quad fuel tanks. Although, I had to run fuel lines from the tanks to one another and then to the engine, getting around the adapter by running the fuel lines to a modular girder mounted on the side of the fuel tanks. The adapters only seem to pass fuel one way, from one to many rather than many to one. But keep in mind I'm a total noob and this is my first post.
