Obs cop
Many moons ago I got exactly the same problem. I went through my PPL OK but when I went to the Air Force and started learning aerobatics (Harvard T6-Texan) I got "that" problem.
Went to several kinds of drugs to aleviate the problem but no way. Then we find out that it was only when I did not have the commands and was somehow "G" related.
So the teaching way was changed. I got all kinds of explanations on the ground and then would go and try to do it on my own without interference of the instructor.
It worked so well that all those badly executed and uncoordinated aerobatics started to make the instructor sick
Well I got away with it and finished the course in a very good position. Later went to the choppers but I never had any kind of problem with those machines. I was trained in Alouette III's and the articulated heads and rotor flexibility greatly atenuated the effects of turbulance and I never had any problem. Those small piston helicopters I don't know. Never flew a single piston hour in my life
