To be honest i don't really have a problem with the advice. But would say its valid for all Flying Schools, be it PPL or Commercial.
And its pretty standard advice from the Moderators in the wannabie section.
Don't pay up front.
Pay by CC
Don't buy blocks with discount.
I would certainly recommend flying around the Highlands using Inv for a base.
Anyway no doudt this will cause weeks of bitching and threats. And make even less members inclined to visit the flying club which is not what I want in any form.
