I bought a share in one a couple of months ago. I love it. As an ex glider pilot, I felt at home in it very quickly. Only a few instruments, maybe not even a radio. But you fly it by feel and it's very forgiving.
I'm 6'1" - flying from the back is no problem and with the skylight, you have good visibility. But in the front - cramped!. Hand starting is a bit of a knack but all part of the experience.
Getting the speed right on approach and landing is important - I'm over the hedge at 50Knt and rounding out at about 45 - stall speed is around 32Knt.
Easy to fly - but a long journey to learn to fly it like an ace. Plenty of youtube videos of people landing Cubs on moving trucks etc. You learn a lot about energy management.
I've only got a handful of hours in it - but enough to say the if you want to fly for the fun of it, then you won't go wrong with a well maintained bit of history i.e an L4 Cub
