Not sure the validity of this because it is Wiki but here is what has been said about it.
"It would seem that the displacement of lift vs weight, and thrust vs drag, would have induced tendencies to yaw and roll requiring continual trimming to control, but the aircraft proved very stable and maneuverable. Indeed Dr. Vogt had calculated that the greater weight on one side of the aircraft could be cancelled out by the torque of the propeller."
