OK all

I need some help, I am in the process of finishing an ARF bipplane that I purchased about 3 years back. When I recived it I did not open it for about 3 months as my bench was full at the time. any way after opening I found it was NOT what I thought I bought so it wasd not returnable and it went in the corner, I have now decided to see if I can make it fly and after looking thru the box and all of the parts there is NO instructions and it was missing the fuse cabaines no big deal so I can make my own. The only making on this thing was a vitercal and horizantal C/L on the fire wall and after measurig the box frame I established a thurst line, Using that as my referance, fitted the lower wing at 0 incidance, it turns out the horzintal stab has 2 deg's of positive, which I think is ok, fitted the upper wing at 11/2 negitive incidance. this matches a 1/3 weeks special that I have. but everything else is different. So with all of the guts in stalled except the batteries. Now I am looking for a way to figure out the correct C/G so any help on how to figure this would be greatly appericated. A singal wing bird is easy but I have never had to do a bipe with out instructions.
