No idea I'm afraid, although I used to deal with them quite a lot (and have many happy hours in my logbook watching Wiltshire go round in circles above my head as we assessed inverted spinning in it) I'm totally out of the loop now.
Seriously however, the RAF took an excellent Brazilian aeroplane and turned it into a much poorer machine. The lack of an effective canopy jettison, 0-70 (rather than 0-0) seats, very high control forces, overly complex cockpit layout and unreliable ECS do nothing to make it a lovable flying machine.
I'd rather have a Brazilian one, or for that matter probably something like an SU-26 than an ex-RAF Tucano to be honest.
Super Tucano
On the other hand look at Pilatus
PC9
PC7
Second hand PC7
Looks like a second hand PC7 might be the way ahead for the rich mans plaything at present. It's interesting looking at the website there to compare the cockpit of the second hand PC7s to that of the newer PC7 Mk.2 which is much less complex and more modern.
