expedite08 "BFC tend to mess people about bit (I have heard). checkouts if you havent flown for a week or something similar! ( possible money making tactics! )"
The management have recently changed and there is a bit of 'messing about' as you put it (have suffered this recently myself) but they operate the standard 28-day rule that most places do.
Their PA28's and C172's are about £25 cheaper if you go for the new diesel versions (as they use about half the fuel), I've not got around to getting diesel-checked yet myself so can't comment on how they fly. I think the cost per hour of a diesel PA28 is £107 or thereabouts so this would be a good move for hours-building.
