I am finishing up my Pizzaz and am really puzzled on how to balance it. First of all, is it better to balance this plane upside down or right side up? Secondly, even with my battery above the gas tank, it seems like I need 3-4 ounces in the nose to balance the plane, this just does not seem right. every search that I did it seems that the plane balances with larger engines. any thoughts?
