If you want me to do a "check out" of any type than I, for the purpose of responsibility for the safe conduct of the flight, am PIC. The deal is if at any time I say "I have control" you take immediately take your hands and feet of the controls and be silent.
When I read this I was curious about the remain silent requirement as it never occurred to me to demand silence from a client if they wanted to ask something....but we all have our own ideas about how to teach and we all have the right to explain our requirements before flight.
If you are not happy with this than I have no problem with that, however I will not fly with you and will suggest some one else who you might ask.
That is fair, do many refuse to fly with you?
