QF, and just what is Aerospace supposed to do with you after you've finished training? They have done exactly what they are supposed to do. Train you to get your various licences and ratings. Whenever I have visited them Sue has made me feel very welcome. Of course, not every one has a great time at flying schools, I didn't at another on Bankstown and I left it.
I have flown at Aerospace and I haven't got a complaint about their instructors. Sue does a good flight test, makes you feel quite relaxed.
There are a couple of good schools on Bankstown. If you find Aerospace isn't what you want, have a look at Whitworth's.
If you have access to a car, I would strongly suggest you check out Liverpool Flying School at Hoxton Park. I did my CPL there. Very good value. Nice small school in the Sydney Training area.
