It was indeed Tiger Helicopters at Shobdon. I went there back in 1999 for a free trial lesson to have my first go in the R22. It was free, there
was a proper 30min briefing followed by a proper 30min trial flight. Not sure how they run it now but I was mightily impressed at the time - unfortunately it was just too far for me to travel to do the PPL(H).
