Cheaper places
Hi EGKB,
May I suggest you take a look at the clubs at Redhill and the Tiger Club at Lashenden/Headcorn.
I think you will find them usefully less expensive. Biggin Hill always was an expensive place to learn.
Or, as has already been suggested, take a look at three axis microlight flying. The TAMs are much better aircraft and cheaper to boot.
Good luck!
BP.
