FreeThinker, I am trying to use your mod but I have encounter some issues. First, every engine I have tested in space has worked with about 1/10 the stated ISP. For Example the magneto plasma dynamic thruster operates at around 1400 ISP with xenon gas in creative mode. Also the beam core antimatter reactor requires 18,750 GW of cooling, is this as intended? I am playing with the world beyond and it's visual enhancement pack, KW rocketry, and persistent rotation, mechjeb and better burn time.
