Except it is being sold as a cheaper alternative which I suggest is not necessarily a truism. Take my helicopter add on for instance. Where it may be possible to complete the transition in 30 hours, in reality, I am about double that (hovering was a real problem) and still see a few more hours to go. And it's not that I do not put the time in, have you ever done an autorotation? That's been another sticky thing to get over.
So while you may have great takeoffs, you could get stuck on landings. You could get stuck on regs. Or like a friend of mine, get an instructor who just could not teach her AND claimed she'd NEVER EVER be a PP. Switched schools after 70 hours, put in another 20 and got her PP.
So you never know.
