I'm 5ft 11", 215 and 34" inseam. Putting on the RV4 is what it's all about.

Once you get it on, it's not that bad.
Due to a broken pelvis and herniated disks in my lumbar I had my seat made for me at Oregon Aero. Without their work I would not be flying.
My seat is back as far as it will go without major mods. The pedals as far forward as possible. For my feet I have some ultra thin slippers that I wear to extend my legs another 1/2 inch. All of this it works for me.
I came to the RV line after owning a Cessna Cardinal 177A for over 20 years as well as a few Citabrias. At times I do miss the room to open up a map or the seat on the right to set my clip board on but I have gotten use to it. These are so cheap to operate it is to the point of being ridiculous.
Try one on, if you like it then adjust the seat to make it work for you.
