Hi Kermorvan,
I don't know if HPG is your closest airfield or not, but it would be ashame if you are serious about flying for you to chose another airfield on the basis of rumours/bad press concerning one flying school.
I am based at Half penny and having visited quite a few airfields over the last few years I can honestly say it is the among the friendliest of places with good facilities and three Tarmac runways to boot.
I am not trying to defend west beach, they certainly do have issues, however there are three other schools on the airfield as well as a micro light school.
If you are looking for friendly professional training then you could try speaking to Andy at the flying school or Bob at Wolverhampton flight training.
Footnote: I am in no way associated with any of the flying clubs at HPG other than as a ppl. I do not have any business interest at the airfield, flying club or otherwise, I just enjoy flying and spending time there and do not want any negative press to affect the airfield unfairly.
