I made the difference in initial purchase price to be in the region of £100k, which is greater than the cost of one full 12 year overhaul. That was my point. Yes it is probable the R22 would be worth less than the G2 at the end of the second 12 year period (before overhaul), but then who knows what the value of a 24 year old G2 will actually be?
At current prices, I'd rather buy an R44 than a G2. However, if the G2 was closer to the price of an R22 the decision to go for a G2 despite unknown future second hand value would be far easier, and lessons would not need to cost £350. That was the point I was making. My choice as a private helicopter flyer would be train on an R22 and buy an R44 rather than train on and buy a G2.
To add balance to the argument, I have not actually flown a G2 (although I know highly experienced pilots who have). However, I did in my initial post state I was arguing purely from a financial perspective.
