Taper angle is highly recommended as they provide: + - Largest area to play with the components and control the center of mass. + - Nice stability (yaw) + - Larger moment in the tip of the flap + +We can manufacture the wing as unrolling its (almost) single curvature surface. This makes it a great candidate to be manufactured in a 2.5 axis machine (likely with a knife as we will need to crease our flat preform.
