Fair point Hill Roller, but a piece-of-**** is not a person so hence it doesn't get my respect.
Just because my questions might not have challenged him it's not an invitation for him to belittle me.
And instead of lashing out and playing keyboard warrior why don't you use words to get your point across such as:
J3 - I did my training at xxx and at the time I was a little hung over and was not really paying attention to my laborious instructor. Now after flying a CSU for a while I realized my knowledge was lacking a little and in the interest of my own safety and that of my future passengers I would like to make sure that I have the concepts of CSU theory firmly locked in my long term memory.
