Plans are great, but better options. A powerful free helicopter can be scored in Far Cry 5 and another companion. Here is how.
Named Adelaide Drubman, she 's looking for her Tempest helicopter back. Located in the Whitetail Mountains above, free the post from Eden 's Gate and talk to her. She'll tell you it has her ex-husband, who's part of Eden 's Gate, and she wants it back. Go to the waypoint and kill the guards.
Once Tempest is located, take to the shadows and wait to get out. Have Cheeseburger or Peaches pounce them on him and take the Tempest. Head back and you'll ever gain access to the Tempest.
