Ive got bad gyro's, did my first and last aileron roll in a t-6 and scrambled my eggs for sure. Flat and upright for me for now on. Got an aerobatic flight in a Stearman and did 4G's in a hammer head, scrambled eggs again. Cant win. Got vertigo in my challenger 440-6pac doing a really good take off in first, gotta just cool my jets with an occasional autocross here and there. Ground is 2D and works for me. Woody
