there has to be a lot of pressure on some instructors working for companies that sell helicopters.
most of the new R44's in australia for instance, are purchased by private individuals who "always had a yearn to fly". unfortunately a good percentage of them should never take to the skies.
this leaves the instructor in the unenviable position of "having" to train them no matter what.
some of these pilots are capable but the rest blunder through the skies oblivious to all as they struggle just to stay upright.
