I am currently building a PDK Mockingbird SSR and evaluating the kit. I decided that I wanted to use internal line connections on my model, so I made two changes to the wing. First, I moved the bellcrank mount to the front side of the spar. This makes the lines exit the wing straighter. Second, since I wanted to access the line buttons from the bottom side of the wing, I turned the spar and ribs upside down and built the wing with a suspended bellcrank mount rather than upright.
Pat has changed the design of the ribs to reflect the forward bellcrank position, and as before, the wing can be built with either the upright or suspended bellcrank mounting depending on how the parts are oriented.
As an FYI, the cable in the outboard wing will go to the fuel shutoff. Since it connects directly to the bellcrank, it has to be extremely smooth and free moving to not create drag in the control system.
