I too had a PPL(A) and hoped to get my PPL(H) in 35 hours. It took me a lot more, and I now think that was a good thing. You can never learn too much about flying helicopters, especially R22s. I recently talked to a very experienced instructor who got his PPL in the minimum number of hours; he said he later discovered just how little he knew about helicopters. At the school where he teaches people never qualify in the minimum number of hours; ditto at the one where I learned. I know some people do at some schools; I wonder how, and I seriously wonder if they know enough to be safe. It's not that they can't fly the thing; you can develop the skills and reactions required in 35 hours. But with a helicopter there's just so much more....
