Hughes 500 always rang me back, was very flexible regarding times, days, & no shows due to me being self employed & on call, + he pushed the exams so as to have them done along with the flying.
I will never be a natural pilot + being old made for some frustration on my part, but he never got rattled when I did stupid things, just explained & said do it again.
He was always on time & ready to go when I arrived, if there were airworthiness issues(
this only happened once) he phoned so as to cause the least inconvenience.
Hughes you will have to stop with the flight suit & helmet way to flamboyant
