Create new cargo hull, add colony module, two Basic Support modules, a 180-degree direction changer, and mount Hyperdrive engine(size-13). Total size: 48/50. When the smaller Ion engines(size-10) become available, it is possible to then add one more Basic Support module(size-5), and increase ship range from 0.8 out to 1.1

However, when I go to remove the backwards-facing Hyperdrive, and install the Forward facing Ion drive, I also want to remove the 180-degree direction changing module. There are so few centerline hardpoints that make sense for an engine mount.

But the module refuses to remove. Selecting it from the componant list (no image btw) doesn't activate the remove button. Selecting it from the displayed model ship activates the remove button, but pressing the button does not remove the direction changer.
