Since KSP v1.1, Squad decided to ‘fix’ the attachment rules of Mk2 fuselages. This has led to some unexpected/inconsistent/buggy behaviour when rotating Mk2 fuel parts, so you may find that some of these parts are flipped over (aesthetics issue only). If this bugs you, please upvote the issue on the bug tracker and message Squad about a fix :). There’s a topic about it on the forums here, PM me if you want the pre 1.1 part config files.

SSTO cargo spaceplane dedicated to Katateochi (with permission), for the creativity and amazing work he’s done with designing, maintaining and updating the KerbalX mod and website. The Katateochi delivers an orange tank and 4 Kerbals to at least 250x250 km medium Kerbin orbit and is very easy to handle. Built in KSP 1.3.1 by Yakuzi.
