O-1 Bird Dog

Anyone around here familiar with O-1’s? Similar to another thread I was searching around for aircraft I could actually afford at some point and the Bird Dog is a very intriguing aircraft. It’s always been one that appealed to me.

I was wondering…what is maintenance like on them? Cost per flight hour?

Financially Im not ready to own a plane now but I’d like to at some point.

Any thoughts? I’m mainly curious if there is anyone around who has had experience with the O-1 or if they know people who have…

(I saw a similar thread to this one, but I started my own as I didn’t want to hijack the other thread with nothing but Bird Dog talk.
