Thrust control modules

The thrust control modules are a miscellaneous item in Fallout: New Vegas.

Characteristics
They can be bought from Old Lady Gibson for 500 caps, 250 caps with a barter or Speech check. If you have the Lady Killer perk, you are able to obtain them for free.

You can also obtain them by killing, or pickpocketing Old Lady Gibson, taking her key and using it on the metal box.

If you have a lockpick skill of 50 or higher, you can pick the lock on the metal box with the thrust controls inside it.

Bugs

 * After completing the quest and obtaining the modules without getting them from Old Lady Gibson's metal box, you can obtain them again from the box and get another module, but since since it is marked as a quest item, you will not be able to remove it from your inventory.
