I have done a lot of playing around, and have noticed that the atomic engine in 1.0 seems to be way less efficient than it was in previous versions. Even though it no longer needs oxidiser, it produces less than half the delta v of the LV-909 engine (the next most efficient engine in the game). I have done all sorts of experiments and there is no doubt this is the case. This doesn't really make sense since it still has the highest Isp. What happened to it? Are there plans to rectify this issue? If not, what can be done to fix this?
