The Hubologists need plans for a vertibird from Navarro

The Hubologists need plans for a vertibird from Navarro is a quest in Fallout 2.

Walkthrough
To start this quest, you must first join the Hubologists then talk to Harry, the scientist next to the shuttle. He will tell you that he needs the Enclave Vertibird plans from Navarro.

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.
