Back when I was eaking out a living as a CFI (leeching off my parents), a couple of local guys bought a Piet...one was going to learn to fly in it, and the other wanted his tailwheel endorsement in it. But first, I got to go pick it up.
The owners picked me up for the hour-long drive to where the airplane was located. I was kind of wondering why we weren't flying out in the one owner's 182 until I saw the strip...600 feet long.
Never having flown one, and not being able to get any pointers from the builder/previous owner (he had passed away...his wife was selling the airplane), I made as thorough a preflight as I could, checked every switch and knob in the cockpit during the runup (2, maybe 3 of them?), gave 'er the gun, and was off the ground in under 300 feet.
Quite an enjoyable flight home, although as someone mentioned, I found it slightly claustrophobic with the trailing edge of the wing right above my head.
No instruments in the front seat, but I could put my Dad in back and have him give me a normal climb, power off glide, etc., so I could mark the struts as an attitude reference.
I ended up declining to give dual, however, because I found the front seat just too claustrophobic.
Fun little ailane, though, and if it wasn't for the claustrophobic issues (which, quite honestly, I have more of than a lot of people), I'd seriously consider one.
