Well, over here it seems you need a rating in order to fly one, so no question of being checked out or not.
There is no such thing in the UK as a tailwheel
rating. You need differences
training and sign-off by an instructor; a rating would perhaps imply a prescribed syllabus, which is not the case for tailwheel.
Turbs are delightful, and too good to risk. I would strongly recommend talking to the Tiger Club Turb team:
Turb Team Home and perhaps taking some dual time in a Condor if available, or a low-powered Cub. And unless yours is a canopied version (the one that was advertised for sale recently?) I would also suggest some air time (as passenger is fine) beforehand in something with an open cockpit .... great fun, but a rather different environment to a Tomahawk or Cessna 172.
Enjoy your Turb; I'm more than a little envious ...
