The ftl drive section is still giving me the issue of NaN but its for the time not ec. I will try again in a sandbox save, I'm not sure how many mods i can remove with effecting my save but i will remove anything that doesn't have parts in it.
The launch plan was a little different this time. We went up till the launch stage got low on fuel. Staged the launch stage and put it just in a stable orbit after the main ship was headed to an ap of 12Mm. The 100% probability was for around 8.5Mm. Successfully jumped to moho. Staged the ftl drive, switched to the beacon just to see what would happen it didn't explode time. However the ftl section is show NaN for time. I added 4 inline batteries to the ftl drive. It has plenty of power.
It doesn't make any sense that i could jump the whole vehicle but not the ftl section itself. I will attach my current career save to my drive folder, if you have time to look at it. I made quick saves from launch all the way to moho. They all start with EWL in front.
