i did my FI course at Heliflight at Staverton the FI course instructor is not an employee of them but i got to know the staff and the general operation whilst i was there.
They are a decent bunch and the chief pilot JL is very experienced and well thought of in many circles.
never a shortage of aircraft and generally quite flexible.
they do PPL upto FI R22 R44 and B206
just my 2 cents
