I use a straight edge ruler and a float bubble. I get one side of the elevator straight, prop the tail up on the plane until it looks level, slap a float bubble on it until it reads level. Then at the very same spot on the opposite side, ( the other elevator) I do the same thing. Most of my planes have the servo reverser, so I adjust the reverser until it levels out evenly to the elevator I adjusted mechanicly.
