Edit: Broke my previous range with attitude screenshot This is the Manta Ray. ~300 stock parts, my pc couldnt handle any more. The biggest aircraft i could create to attempt the world tour. Made it 2,313,338m far within all rules of that. I added my own rules to this which are: No droptanks and no jeb mech. In the end my aircraft expierenced uncounterable tailheavyness since all the remaining fuel went into the back of the plane, which was a waste of about 1200kg fuel when i managed to 'land' it on the water. Still havent found a solution for this.
