Jim,
I don't know anything about the Slob's history beyond last year when I got my first one. It is a fun plane to fly and really does well as an exhibition plane.
Since we have a thread going, I'll toss in a picture of my Slob#2. I gave the first one to my friend Jan after I'd pretty much flown the covering off of it. John Paris put #2 together for me as a Christmas present. Thanks John, You did a great job.
