After I started blood pressure Meds dropped my G tolerance a bit.
Also found out extrema heat and sun effect can effect tolerance greatly.
You know you have pushed the edge a little to far when you release and all you can do for about 15 secs is hang on and fly level. And you a clueless which way you are headed.
Havn't tested my max in long time,did 7.5 in L39 dog fighting, once with Bob Shaw we were finding the corner speed of my RV. Bloody bob is a short little guy and has a greet tolerances, he Kept us at 6g's for about 45 secs of soda straw , my eyes finally went way black, but didn't g lock since he release shortly there after. Other wise 1 or 2 more secs I would lights out.
Same day we had lots of fun seeing who could loop from lowest starting speed. But not a lot of guys want to go up to find max G's so I don't get to push the edge that hard alone.
