This post is to answer all of the tail brace wire questions for Carbon Cub EX owners and builders. The Carbon Cub Ex (CCK-1865)has always used the Top Cub/Super Cub type tail brace wires along with the wider Top Cub elevators and stabilizers. That means that Safety Alert SA0009 does not apply to the Carbon Cub EX (CCK-1865). There is one Carbon Cub EX that does use the the Carbon Cub SS tail brace wires and it's designation is CCK-1320 which means that SA0009 does apply to this Carbon Cub EX only.
