thats what i\'m actually doing. im still flying for 1 1/2 hours(99% without engines) and used 40,8kg fuel so far. i need something about four or five mor hours to reach the facility so i think i will stop now. its unbelievable boring. but i am sure i could do this with less than 100kg fuel. if somebody tells me how to use the spoiler-function i will edit my post.
