Randy-- where did you get the info about the paddle prop on the Cavaliers? The paddle prop was just the next in production from the cuff prop. The cuffs where mainly installed to provide a higher ram air effect into the air inlet (smile) for the engine. They did however have a secondary effect of torsonial problems as Jimmy mentioned. I would believe that the paddles where on the Cavaliers more as they were the later props that the airplanes came out of production with. Towards the end of the war, the paddle was the prop that was in production.
Sorry if I made a muddy statement there...I wasn't saying that they used Aeroproducts props on the Cavaliers, I was saying why they did NOT use cuffed props. They DID use the Hamilton Standard 24D50 with 6547A-6 blades.
Got that info right from Bob and Ed Lindsay -- their father and his people believed the cuffed props were apparently a better prop from a performance standpoint, but the possibility of corrosion under the cuffs meant it was an increased maintenance item.
