I highly suggest you take a F4U up in TA, have someone you know go with you, aim for your wing-tips, shoot them off, (just one) and then do your regular ACM. I, for one, cannot. the only thing I can do is dive for home, and nurse that puppy all the way.
Sure, I can turn it once, maybe even get away with turning it twice, but once that energy bleeds to under 150 kts., then you get a wing stall effect thats almost impossible to pull out of if you have no alt.
The F4U was a tough bird, known for taking alot of damage, you see, the 109 was not known for that.
