Works like a charm in outer space. Don't know why anyone requested one since there is noting to travel to yet. I haven't tried it as an orbital stabiliser but i think it will be to weak to manage, especially a reentry burn. I must say that it looks so fantastik, I will be using it on some of my rockets just for looks. It could also use a different fuel tank, it just doesn't mach up vanilla one i my opinion. If you really want to travel forever I recommend paring it with XLfuelTank. I'm still waiting for that 1965 Chevy
