Thanks dmanson: I hear you on the servo conduits. I have been reading and re-reading the instructions for the servo bays. Quite frankly, the pics that Sig provides in the ammeded instruction sheet are lacking. I have studied both the drawing and the pics and still have a question or two. As I see it, the basswood? mounting brackets just attach to the ribs on either side of the servo bay and then must be sanded to match the contour of the wing rib. At least that is what it appears. Is this correct, or is the mounting method different? It seems to me that the ribs are somewhat light in weight/strength to hold servo mounts. May not be the case, but I did question it during my reading.
