mr sasless,
I can see a requirement to operate out of a controlled airfield at some point in one's training but all of one's training?
a licenced airfield does not neccesarily mean that it has an ATC service, there are many examples of licensed airfields with A/G service, where effectively you are doing what you like.
e.g. white waltham, leicester are the first 2 i can think of.
regards
CF
