Well after a month of playing I created the OSI Tempest MK I quite by mistake. I was trying to make a craft which was exceptionally well balanced for gliding, yet pretty maneuverable. It ended up working a tad better then expected. When I took it up for a high altitude glide it just kept going and going. Eventually it made it to space. So a very happy accident. You end up with a 4th of a tank of fuel usually. Enough to make it to Munar Id suppose. http://imgur.com/iA0wvmO In anycase the picture I posted has the HOME thrusters instead of the tail rocket like the base model, but performs exactly the same due to design. Hope ya guys like it
