I think my C172 check out was about an hour
Just a slight note of caution that it may take a lot longer. I know of a number of people, in which I include myself to an extent, that effectively learned to fly a particular aircraft type, rather than learning to fly.
When I first flew a 172 my landings were hopeless and it took a friend to point out that I just wasn't looking in the right place. I was quite able to do beautiful landings in the aircraft I learnt on, but the technique I was using was evidently very specific to that plane.
If you find it doesn't come easily, take a step back, re-read the text books and you might discover something simple that will just make it work.
