Ghengis, you know, whats the deal?
I don't know about the defence sales issue, but I know (or at-least knew) my way around the Tincano pretty well.
A pretty aeroplanes, which feels like a jet fighter from the inside. I'd personally judge that it's much less within the capabilities of a PPL than something simple like a Yak-52 or BAe Hawk. It's also a fairly unreliable device, and I think that in civil hands it'd be cripplingly expensive to run. You'd also have to persuade CAA to allow it onto a Permit and convince them that you had the full capabilities to maintain it.
On the other hand it's an 1150hp 2-seat turboprop, with a military cockpit, roughly the same size, shape and power as a Mk.1 Spitfire. It's a little known fact that the UK versions also have the export weapons hardpoints still fitted as well, although they've never been used.
Personally if I was looking for a toy like that I'd buy a civil Pilatus
PC7 if I could get one, cheaper, more reliable, better handling, and available off-the-shelf with a CofA.
