I'm thinking I would like it to come out around eight-ten pounds ready to fly. I will power it according to the final build weight. Likely a .91 four stroke, but I've also been toying with the idea of doing around a 130" span and powering it with a spare O.S. 1.60 FX. My goal is to have enough power to get off the ground in only a few feet and have an excelent climb rate, but I really do not care about speed or aerobatics in the least (at least not this plane). I just want to have a relaxing sunday flyer that's big enough to be interesting. A flat bottomed airfoil would be perfect, and if I can get a good suggestion, I could probably print it out and blow it up to the size I need. It will be throttle, rudder, elevator only.
