Do a search on here for 'ravenair' and 'liverpool flying schools.' There has been a bit posted about them in the past with some quite useful info.
Think Ravenair are a decent set up but apparently you can struggle to get flying time depending on how many UAS folk are going through there as they get the priority.
Worth a visit to the offices if you haven't already been, they're friendly enough, just make sure you ask about the UAS numbers!
