The LWA's field of view advantage can be a thermal disadvantage. HWA pilots enjoy the shade of the high wing. LWA have more of a greenhouse effect, especially those with bubble canopies. To make gravity work in the same manner in the LWA, the pilot must roll upside down. The dihedral effect is the airplane's rolling response to a sideslip.
Right stick is needed to prevent the plane from rolling left.
It wants to roll left because left pedal deflects the rudder trailing edge left, which causes a left yaw. Holding the pedal maintains the left yaw, and this means the relative wind is coming from somewhere right of the plane's nose. How far right is called the sideslip angle. Airplanes with positive dihedral effect roll away from the sideslip. In this case, the plane has a right sideslip, wants to roll left, so right stick is needed to prevent the roll.
