I bought a Sensenich Wooden W72GK-44 for my Cub with a C85 after overhaul, but it is too fine pitched despite being the only one listed by Sensenich. Who has RPM/cruising speed figures with a -46 and -48?
I am hoping for >70 knots @2300 RPM (72% power). I got 75 knots with my previous Metal 76AK-2-42. Thank you. TOM ([email protected] / www.tomair.dk)
