Knife Edge Switch
Wouldn't this prevent the roll coupling even at a low airpeed and induce a true yaw.with rudder input...This is a problem with bipes in a flat turn....which i consider knife edge in a horizontal plane....
Of course the side load of wind against the fuse is not as pronounced .........
Seems like if you had the plane flying in true axis control inputs ...everything would fly better........
I fly IMAC type stuff..btw
