Leave San Francisco and head to Navarro, southwest of Arroyo. Once you arrive there, you can either convince Chris (the gas station attendant) to let you in or kill him. After gaining access, enter the shack on the left and interact with manhole. You should now be in the base.
Go down the hallway. Skipping the first turn after leaving the hallway, take a left. You should come across a room with lockers. In these lockers are a full set of power armor and a plasma rifle. You will need to equip both of these items in order to fool the characters that will appear later in the quest.
Further down the hallway is an elevator which can be used to reach the top of the compound. After reaching the top, go to the hangar on the left and talk to the man named Raul. He should direct you to Quincy.
You should now go to the hangar to the right of the elevator, where Quincy is standing near a locker. Talk to him and tell him that Raul sent you. After some minor complaints, he should tell you that they are in the locker next to him. At this point, you can return to San Francisco.
Back at the Hubologist compound, talk to AHS-7. Give him the Vertibird blueprints to complete the quest.
- If you give the Vertibird plans to Matt at the BoS outpost he will give you a copy of the plans and 20,000 XP so it may be more useful to give the plans to him first.
- There are many other things you can do at Navarro such as:
- Also getting the plans themselves nets you 3500 XP.
