It's been a few years (about 18
) since I started off as a PPL which I did on a Super Cub at Clacton who were then considered to be one of if not THE place for tailwheel training.
I'm certain the instructors are a completely different bunch these days but I'm sure they're worth a look. Back then they were also about the cheapest, my lasting recollection of places like White Waltham, Elstree and Denham was £££££.
