Just FYI, Sensenich advised me that you do NOT need a return authorization if you are returning your prop hub. They said just INCLUDE the plastic pitch cylinder and send it along with the hub to the Plant City address. Include your name, address, and telephone number.
( I see no pitch change or looseness on mine, but am sending it back for the "repair" job anyway to head off problems that might arise in the future.)
