That engine & prop combination put out LOTS of torque!
If I remember kee-recktly, the powerplant & prop were the same as the B-29. 2,800 + HP
The F4U didn't get certified for carrier duty right away. It took the late-war carriers to be able to handle the Hot Rod F4U series! I think the Marines had them in quantity before most of the Airdales did - the 1st Navy Corsairs were only OKed for the few Naval land bases. And they were pretty much side-by-side with the Marine F4Us. I think it was not until mid-to-late '44 that the carriers routinely had them. One of the primary problems was take-off speed, and the British catapults were adapted for American use primarily so the Navy could use Corsairs. My Dad was part of their testing (the cats), but he never flew an F4U ... he said he got to taxi one once, but never got certified to fly them.
