The following are the details of what has been dubbed "Big Bird".  Oddly enough, the plane only has a 48" WS.

With the above set-up, this plane easily does ROG take-offs.  It really only needs about 6 feet to get up and out.  It flies slowly enough to be used as a trainer, but will also keep up with the .40 sized glow-powered planes.  It's not very aerobatic, but will loop, roll and do some non-scale maneuvers. 
Oh, yes, even with the small-ish wheels, I fly off of a grass strip without issue.
