Hairpin turns

I am sure this has been asked but my searches have not gave me a solid answer.

With the small fast fighters, how are the very sharp 180 performed? I am on Windows, Keyboard with gaming mouse

Well this depends on the fighter really not all can do it if you are BF you can use ‘‘Q’’ and ''E" for sharp turn corrections since its a sharp turner specially at high altitude but you cant perform the same a lower then 1000. You will have to describe exactly with which plane you are trying the sharp turn and keep in mind are you low altitude fighter or high altitude fighter. Some planes perform better above 1000 others better bellow 1000. But really depends on the plan not every fighter can perform them.
