First, the stab is a flat slab type, no airfoil there. The wings look to be full symetrical, or nearly so. The stab sets high, maybe an inch or more above the wing. I was thinking this guy weighed a ton, but when I put it on the scales, it came in just a tad over 11 lbs, but that is without the battery.

The 6 1/2" sounds closeer than what the caculator suggested. I've attached some photos of the plane, I found the relation between the rudder and elevator to be somewhat unique, based on the searches of plans and kits of that size plane. It could well be that it was a home designed plane, I'm sure it was scratch built as there is no indication of die cut parts that I could see.

Thank you for your input, I'll install the battery and balance it out today and see if it may run, first problem, then fly tomorrow at the club meeting.

By the way, if anyone recognizes this bird, please let me know. When I posted some photos just after I got it, there was a lot of guesses that it was Bridi (Sp?) design, but looking over all of his kits and plans that I could find, none were the size of this plane, and none had the rudder/elevator relationship this one has.

PS, I'm going to fill the 3/4" gap between the spinner and nose ring after I find out if it flys OK. The O.S. 1.20 pumper fit the motor mount that was in the plane but I had to mill clearance in the top of the mound for the regulator. The cowl must have been built around a two stroke, given the hole for a needle valve extention and the short nose compaired to the four stroke.
