When I have built, there are two things I have wanted very much: 1. A MK2 ending that is like the cockpit except with the top being flat so that I can make standard tubebody airoplanes without needing to use the mk2 to mk1 adapter and then something else after that to make it end smoothly 2. A MK2 Ending that ends up as a flat plane, so that I can make a blended wing and body design, and attach ailereons or other control surfaces after the ending, as well as attaching wings until the very end of the main body. This could be made by just flattening one end of the mk2 half length fuel tank Thanks so much for reading this, and if either of these are available in a mod for the most recent KSP, I would really appreciate it if someone could put a link underneath. Thanks for considering, and I wish you a great day.
