Very individualized cockpits
I suspect there isn't a good generalization to be had in answering this question. I know we built our -3 cockpit to fit us and it's perfect. However, a big guy (say, 6'2" and 230#) would find it too cramped. The pedals could easily be extended, the side compartments removed, and the seat replaced with something thinner and allow a much bigger person, but they won't fit right now.
The -3 (and, I believe, the -4) aren't nearly as cookie-cutter as later models so you can't generalize on the fit very well. You just have to try each individual plane on.
