that would be the problem then. Thanks! *edit* also, I think in the .craft I linked I had removed the fuel lines on the outside boosters.

What I mean is that the first set of tanks that empty are emptying at different rates. it might be that I had the outside boosts linked in with fuel lines, I took them off as well as the engineer part and it worked out. this is just a horribly designed rocket. guess I need to buff up on docking, not that good at it....

I need help with my rocket. it isn't *too* big, 468 parts. it's a lander with a 4 side engines and a main, with 5 nukes under that, then an orange tank with a skipper, then the main lift with 2 orange tanks and a mainsail with a 6 way asparagus with orange tanks and mainsails and an extra orange tank with mainsail off to the side for a bigger initial boost. I am trying to land Kerbals on the other planets, this probably isn't a good design for it but the trouble I am having is the initial lift off. if I put all the outside tanks feeding straight in I have no problem but when I put it into an asparagus arrangement the first tanks get messed up in flight somehow. one side is emptying faster than the other. I have checked the fuel lines a number of times and it looks right to me. if somebody could take a look and tell me what is wrong with that stage I would really appreciate it, also any advice about how to engineer this better would be great. Thanks in advance. http://www./view/v6g9eynp20xxg84/4_7.craft mods: http://kerbalspaceprogram.com/0-18-1-kerbal-engineer-redux-v0-5/ but no parts installed on ship.
