heres a small pitch or ya, if im seeing this correctly your putting 2 nacelles on one pylon per side, BUT i had this idea for the arsenal that the 4 nacelles would be in a "lay" down pattern in combat mode, and then have to MVAM into the x shape for warp, unfortunately the nacelles were too damn big to pull it off, but i think you could make this work with this design, keep your nacelles in the pattern shown on the dorsal view, have them lay flat for normal impulse cruising, and then MVAM them to the x pattern like the X-Wing fighters do. just a thought, keep up the good work!
