No probs here either. I would do the following:
Set flaps to 100%
Run engine up to 100% and hit War Emergency power.
When you drop (literally) off the end of the deck, then
ease back on the stick, bring your gear up, wait until the sink rate drops and stabilizes, then begin to bring your flaps up.
Launching in a fully loaded F4U-1D or 1C (100% fuel, 8 rockets, 2k bombs) has never been an easy adventure, and our particular squad revisits "CV OPS" once a year to re-qualify so that we don't accidently lose any aircraft in the Special events "Tour of Duty" due to something stupid like "basics".

In our CV ops, you must launch, and trap off 3 consecutive times in a row, with the same airframe
without backing up on the CV.
