The HOTAS was not that complicated as far as the stick goes, but the radar hand controller was a work of genius! The story told to me was that it was designed by a blind person andI can believe it. The exact number of functions escapes me in an alcoholic haze, but the control you had over the radar and the attack displays was phenomenal. I have an early generation controller that I am still figuring out what to wire up to as there are too many oprions.
