Awesome project Bill.  I did one around 50", and would like to do another.  You may motivate me, as I've been on a 190 kick lately (favorite plane) and just finished a 16.5" Guillows rc 190 that I'm optimistic about, and was not my first crack at it either.  The big 50" one got a bit tail heavy, and I was discouraged with the necessary noseweight needed.  I gave it to a glow flyer, who I need to get on, about getting it in the air.  He got it with servos and all, basically as a motor/receiver ready plane.
