Europa-List: Play between elevators

[Ronald J. Parigoris <rparigor@suffolk.lib.ny.us>]

Curious about play between elevators.

On planes flying, if you grab the left elevator with left hand and right 
elevator
with
right hand and move them in opposite directions, what is the amount of play 
between
them?

I know there is a mod to replace 1/4 inch drive pins with 3/8 pins if there is
more than
a 1/2 inch of play between the 2 surfaces.

Thx.
