Where is the C.G. for a PICA Bucker Jungmeister Biplane?

I have what I believe to be a PICA Bucker Jungmeister Biplane. The wing span is approx 60 inches. I acquired the plane used I refurbished it and now is ready to fly. The only problem is that I don't have the plans to determine the C.G. Anyone who can provide any help, I would really appreciate it!!! If you have one of these planes, even if you tell me where your plane balances it will be a good check for me.

Thanks
