They had a lot of handling problems & most were solved or contained by workarounds & design changes. The roll coupling was helped by the Stab Aug system & I think it was the Navy or Bauer who first saw the pitch up problem in the design. From memory, that was fixed by the dogtooth outer wings.
Also, at a certain AOA, putting the stick to the left would result in the aircraft turning right. I don't think that was ever fixed; they used their rudders a lot in that situation to turn. Mostly due to their spoiler/drooping aileron setup creating drag.
It was certainly no air superiority fighter & would go into a spin at the drop of a hat if the pilot didn't hold his mouth right.
But I guess it was a big powerful lethal beast and people had a healthy respect for it. From what I can gather, it had to be flown fairly precisely or it would bite. Flying Brick sounds about right.
At least in Vietnam when they came up against the MiG-21's & the old MiG-17's, they had the power and speed to dis-engage, as they couldn't effectively dogfight. Different days; it's all a bit more technical now.
Apologies for getting a bit off topic from the original post.
