Try instructing on Microlights - not the weight-shift thingy's, there are real aircraft as good as C150's, Tomahawks etc out there to fly. Some even have glass cockpits. Your don't even need a CPL a PPL will do and the pay is about £50 plus an hour. This is where the career instructor needs to migrate to, leave the hours-builders willing to work for peanuts on group A behind! Have fun and get paid well!
