  1. images in spoiler The only mod I have is mechjeb. It has been a while since I played KSP, but recently started again. Today I just unlocked the big orange tanks, and because I have potato PC I thought great, anything that reduces parts is fantastic. structural stability is great too. Since I had plenty of tourist missions, I decided my first use of the orange tanks would be to give an older tourist shuttle a slight revamp. However, I ran into a slight problem. Despite the orange tanks appearing to be identical to 2x rockomax x200-32, it seems on my game this is not the case. Despite the client displaying them to be identical, and mechjeb showing identical TWR and delta v, when it comes to actually using them it is a completely different story. The only difference between these two rockets, apart from the tanks, are fuel lines and struts, which are placed in the same manner but will just be in slightly differing positions. The shuttle part of the rockets were not changed at all, in fact I even left the solar panels which clip through some fuel tanks just to remove as many variables as possible. I have tested the orange tanks in a handful of ways, (including with the solar panels fixed) and every time they lose out to 2x x200-32. When it is just a probe on top of the tank/s and a mainsail at the bottom, the difference is fairly slight. However, it becomes even more significant if I use the pictured vehicle but remove the first stage radial boosters. Mechjeb claims a TWR of 1.61 for this instance, but as soon as the structural supports are released it will actually fall towards the pad. The x200-32 stack always takes off with decent acceleration. At the moment, it isn't much of a problem. The numbers of parts I could save by using these tanks over other types is minimal. By the time it reached a significant number, the rest of the ship would cripple my cpu. I am very frustrated by it though because of how odd it seems. I haven't noticed (but haven't checked either) of similar issues with other synonymous parts. I have already validated client files through steam. I am very happy to upload the craft files, I am just not entirely sure what a good place for them is. Somewhere that doesn't require sign up would be great. tl;dr: orange tanks appear bugged on my client edit: image link fixed(?) the second ship in gallery I forgot to show the engineer report in bottom right side, but weight is identical, H/L/W etc all identical or near enough. I have ran other tests all measurements identical, the only things that haven't been tested to be exact are cost and the part count is lower by one or two I think, simply by using the orange tanks instead of the x200-32
