Well, I managed to get this into a 76.5-79.5km high orbit with half a standard fuel tank left to go higher/ come back down with. It\'s got 6 gimballed engines drawing from 7 fuel tanks to get you up (hit t and it\'s dead steady all the way), then one non gimballed engine from two fuel tanks for getting your orbit and what not. I initially tried it with the little rocket engine on the second stage, but it couldn\'t achieve orbit before you fell back into the atmosphere. The lander is just a glider, no fuel or engine. I was shocked at how stable it was. Let\'s not talk about my initial attempts at a side mounted lander... So many crashes...
