The arms pictured here form a complete shape all the way to the backplate of the brake. I will be testing an SL version which gives up some of that complete shape in order to save a few grams. Wind tunnel testing will determine whether I produce one shape, the other, or even both.
As the prototyping phase of my Omega brake project continues, I wanted to share the SLS plastic prototype that came in. It reflects the current state of the design, which is nearly ready for production. Check out the article for more specifics.
