As air flows over it, a force like lift results, and the tail is pulled in the opposite direction of the deflection. But instead of an upward force of lift on a wing, it’s a horizontal force pushing the tail of the plane causing the nose of the plane to move left and right. Why is this? This is called adverse yaw.

This creates boundary layer separation, resulting in a loss of lift. The lack of airflow over the ailerons results in a loss of control authority and mushy and ineffective controls. Watch out for torque effect (especially if you are in high-powered aircraft) since the increase in power can cause the nose to yaw to the left.

Another advantage of the counter-rotating props is the elimination of torque roll. This is the tendency to dig in the left tip float during takeoff while countering engine torque. The airfoil is a Harry Riblett shape, giving modernized flow separation on the leading edge for a soft stall yet with good lift and drag performance.
