Hello,
I have a new to me Starduster Too. Built in 1982 with an O-435. Heading to Oshkosh later this week and am curious what others with the same setup are using for a prop. Currently have a Prince 76x66 and does not seem to want to spin up to the correct rpm. Previous owner had installed a Culver 78x58 but that had developed a crack on the trailing edge. The Sensenich books shows W85RW or RB -57. The hub is a 41G2325-9
Look forward to your thought and recommendations,
Dave
