Again, just like the real thing. Almost any two/three winged airplane built before 1930 will be a rudder/elevator airplane. From what I have been able to gather, the DR1's ACM was being able to turn without banking. It's pretty unstable, directionally, and was able to give the following airplane no idea which way it was going to go...Well, it couldn't actually catch anything, and certainly couldn't run away...
