OK stickbuilder I am confused! Like I said I have never flown a Biplane before so this is going to be a learning experience for me! Are you saying that the direction of travel down does not need to be as much as the travel up! And yes I know about using rudder. My warbirds have made me start learing how to use the surface on the tail!

Before warbirds I corrected on approach with ailerons and elevator! Not the proper way but the extras and edges were forgiving. Imagine the surprise the first time I had a corsair on final and did that!!!
Most modern radio systems allow you to install differential by using the programming in the transmitter. On most Biplanes, especially the Waco F series, when you apply left aileron, you want the left aileron to rise. and the right aileron to droop. Differential means that when the left aileron goes up 1 inch, you want the right aileron to droop 1/3 to 1/2 inch. The same applies when you add right aileron. Adverse yaw comes into play when the drag from the down aileron causes the plane to yaw toward the low aileron, even when you are making an opposite turn. Its something that you have to adjust during your check flights. Adjust the amount of differential until you don't notice any adverse yaw.
