Thanks for the replies.
My location is out of date, sorry. I'm based in the UAE. It's almost impossible to hire aircraft here, and when you can find somewhere, prices are high. For example, a C172 is around £170/hr.
So, Genghis, Aeroprakt A22 wouldn't really count for much, but you think the FK9 might. As you say, I'll check with the CAA.
Cheers.
