Graybeard, I've got one of these that I bought already framed up. It was built with contest grade balsa with the intention of having a light setup with a 90 fourstroke on it. I put a an MDS 1.48 on and it balanced perfect and weighed just a hair over 11 lbs. Best flying plane ever.
After a few wrecks and some mods (fiberglass cowl, rear mounted elevator servos, antivibration mount) its at around 13 lbs and although still flies nice it could use more power.

Yours looks GREAT!
