The lightweight bulkheads lower the CG, and have 2 centering pins instead of one to get more consistent alignment and better tweak opposition. The bulkhead is a 1-piece tweak-free design which rigid and robust. The bulkhead features upper and reduced centering pins that align top of the and lower pod dish during assembly and stop motion involving the elements in case there is a crash. The 1-piece bulkheads use scaled-down eccentric bushing inserts for the back axle height adjustment. CNC-machined from premium extra-hard Swiss 7075 T6 black-coated aluminum.
