Hi
I think you need to have a look at the PFA or LAA site, try...
www.pfa.org.uk/S%20Mac%20Website/Specification%20Sheets%202007/BushbyMidMustang.pdf
for starters.
My understanding though, is that it can be a problem to fly PFA / LAA permit aircraft outside of the UK and that specific authorization is needed from the country concerned so you might have a problem if you want to take it home.
