I did make a few little tweaks to personalize it, but the basic airframe remained the same. Even with four external tanks, I had to cut burners halfway through the trip to make sure I would make it. Very fun plane to fly, both responsive when needed yet still stable to fly. Always happy to see pilots enjoying my planes (or derivatives thereof!). I was a bit surprised at your findings that you needed any extra fuel tanks at all, considering that I've circumnavigated Kerbin with the fixed-wing original, let alone on a much shorter DSC-KSC run. Made me wonder if there's a marked difference in fuel consumption between 1.3.1 and later versions. Or if it was caused by the extra drag of the variable-sweep redesign of the Mk2. So I went and did the DSC-KSC trip at full afterburner blast in 1.12.4, with the MK2 since that's the draggier, slower, and fuel-hungrier version of the two: Departing from DSC with the default amount of 950 units LF in the tanks. Engines set to wet mode from the start, no expenses -or fuel- spared. Spoiler Flight profile was to climb as rapidly as possible to the 20-21 km cruising altitude and then beeline for the KSC. Some time and absolute top cruising speed is lost, yes, but I find it is well worth it even on a speedrun, with maybe the exception of very short trips. Jeb even took the time to play with the variable-sweep configuration, because why not. KSC in sight, Jeb decided to throw caution to the wind (and mute the engineering team) and dive full bore towards the runway. Perhaps the engineering team had reason to warn him. Kraken-flapping took the rotors, wings, and one of the engines. Oops. Non-plussed as ever, heck even with a smile, Jeb continues his approach as if this were business as usual. (It usually is for him.) Even sans main lifting surfaces this plane proved quite easy to set down gently. And this is 19m18s later on the KSC tarmac. Flown at full throttle wet mode, cruising at mach 2.7+ and peaking in dive at mach 2.9. Still 624 units LF left. And it was by no means an ideal run - see the spoiler for some flight details. My SPH engineers respectfully but categorically conclude that whatever caused the high fuel consumption was not due to the original plane design...
