When I visited the UK back in March of this year, I put a couple of hours on the G2, just to get the experience, and it cost me £432 per hour dual including VAT for a total of £864.
Here in the US, in an R22, those same two hours of dual would cost me $275 per hour including all taxes, for a total of $550, or £408 at the current exchange rate. Less than half! A bit of apples and oranges, since there are exchange rates in there, but quite a dramatic difference!
Cost not withstanding, I definitely found the experience worth doing once, as expensive as it was for me. Indeed, looking at VF's thread, he just proclaimed the G2 the best/easiest to auto-rotate after the 407. No wonder I thought it was so easy to auto
However, the cost differential between flying Robinson and Cabri falls into the category of fly or don't fly for me, and the risk/reward calculator that lives somewhere in the mushy thing in my head has calculated that the flying is worth the risk.
