You're exactly right! The torque was amazingly strong in proportion to the frame. It's like that old science experiment from school; sit in a wheeled chair and hold a spinning bike tire. When you angle the tire you get whipped around. Same thing happened when you angle a spinning prop while sitting in what is essentially a box kite. Rudders would try to take you downward while the prop whips the plane to the right. Boom!
Fascinating stuff. (to me!)

Howard Hughes' film, "Hell's Angels" has some of the most authentic (and expensive) footage of WWI dogfights as he used actual WWI aircraft and staged amazing dogfights for this film!
