At a suitable location, one could set up a really pro flight training business / flying club, with decent modern aircraft, and certain management practices that would encourage people to stay. I have not seen it done yet.
I have, quite a few in fact. But they tend to fly aircraft with whirly wings.
Helicopter schools don't have clapped out old machines, because R22s at any rate get rebuilt at 2000 hours.
And at a lot of helicopter schools, there are enough machines that you can usually hire one at short notice, and take it away for the day - or even a weekend. And I suspect this is what really makes all the difference to people.
And for those who actually care about such things, helicopter flying is considered as super-cool!
