I havent done any tests to see if things are different between F4U's but snapping the wings is easy to recreate, it just requires the right conditions.
You have to go fast enough that you do not enter an accelerated stall, and you have to not be going so fast that your controls start to become sluggish.
I think somewhere around 450-500 works, crank the stick back hard and there go the wings.
*note if you have your damping set to anything but 0 this may affect your results as it delays your flight inputs.
As for whether this affects one F4U other the other, I have not personally noticed a difference at all. Ordinance will make a drastic change, perhaps that was being carried more often than not in the other models?
