This mod is not known to work with the latest version of Kerbal Space Program. Proceed with caution.
I think the stock ISRU system is missing a critical part: The ventral (in-line) drill. This simple mod fixes that. It adds a ventral drill that in all other ways (Tech tree node, mass, usefulness) is the same as the stock radial drills.
I did not make the model. That credit goes to Nertea. It's the same model as the ventral drill from Karbonite, with a new name and stats so it can work on stock ore without having to install Karbonite. You should be able to install this along with Karbonite but there is no reason to.
I did not create the stats. All I did was copy the stats from the stock radial drills (for ISRU stuff) and the Karbonite drill (so it mounted and functioned correctly).
So in short, this is not my work. This is a simple retooling of two things to make a new thing.
Raw stats are from the beginning of time until now. Each follower and download entry represents one hour of data. Uneventful hours are omitted.
