This is the very same thing i've been discussing with others in the P38 wingloading thread.
Try doing THAT in a 190 or 109 on full WEP. The plane will fight you and kick you around the moment you get below 100mph. A g10 wont even let you recover, it'l push you into a really, really nasty spin.
Yet N1k, spit, F4U and im sure many other planes (I personally have not tested this on any other rides besides the 3 I just mentioned) can hang on prop when fully gassed, full wep. And we're talking here about a lightweight plane with a MF huge 1990HP engine and about the one ride in the US arsenal famous for its strong torque issues.
Sikboy, here's what I get:
Full gas n1k, full ammo, take off, get it to 300mph, pull nose straight up, WEP it. Keep nose up and watch your speed... you will notice that its not until 55 mph that the plane will BARELY start to roll to a side or wiggle nose up and down, but its so slight you can compensate with extreme ease. Once the n1k gets to 20mph, it ALL BY ITSELF noses over in an instant, the moment the nose is pointing down you have complete and absolute control of the plane. No spin, no stall, no torque tumble. Do the same test again, this time FIRE your guns all the way up. You will lose speed faster, but the same thing will happen, even if you keep firing way after the plane noses over on its own.
Do same test with the F4U-D (or -1 or -C or -4). The results are almost identical. The only difference is the hog will complain and fight you more than the n1k does below 100mph, but its very easy to keep the nose up. Then, when the speed drops below 40mph the F4U will also "flip" the nose over on its own. IF the pilot tries to compensate it will spin, if he doesnt, it noses down on its own.
And as I said before, if you were in the pre-fm change AH, you would remember that the torque on the F4U was a paramount, ever-present issue. You couldnt even do a LOOP because on the topside the torque would spin you out. You had to chop throttle down to half or 0 on the topmost part to not spin out. That was awesome!
