Thanks for your replies.
In terms of looking for groups / rental, how do I go about doing this? I've tried searching online (e.g. 'Damyns Hall flying group' or 'Damyns Hall aircraft rental') but I'm not finding many results - other than flying schools. Is it just a case of calling the airfield directly and asking, or paying them a visit? Apologies for this basic question - I've only ever flown with a flying club and a chap in Bournemouth who had a website, which is how I found him.
Earl's Colne would be fine, I can drive there. Any more info on the groups / operators there?
North Weald would also be fine - but the costs add up (£65/month group membership + £60/year insurance waiver + £160/year club membership + £200 deposit), not forgetting the actual wet hire costs, which aren't cheap. Are there any other groups there?
Thanks again everyone - appreciate your help.
