Hi there, here's how i went to Eeloo: First, assembling ship around Kerbin : third part : after part 4 and the lander, i went to a minmus orbit, then did a refuel mission : i then had above 7500 delta V, so time to go: Ship returning to kerbin (strangely, flight engineer got stuck after complete assembly of the ship): Score : i had 3 assigned groups to get "surface", "near" and "high over" in one trip. Too bad i forgot a thermometer, an eva report, and all crew reports. 12 nuclear engines is enough to go to Eeloo in a few minutes from minmus, if i had to redo it, i'd probably would separate my nukes, so i don't end up with 8 on the return flight, might save some fuel can share the .craft (s) is somebody is interested, only mod used is flight engineer part 3 was tricky, so i ended up emptying the top tank first to loose weight on top my ships are beetwen 200-350 parts each
