Thanks! Atleast someone's still in my court!
I will admit I can barely fly one rev but what if you made a static 4 line handle in the shape of a plus sign. You would only have inches of movement but that should be enough in this way you could control the line lengths without having to exert the strength of holding two handles. You could event mount a handle the middle pull back for up down for down twist left or right etc. Maybe someone should look into this for amputees that want to fly quad lines.
