I need to know how many ribs are under the wings center sheeting? I went to GP web site and found the bal. point to be on the main spar at rib
- I can reasonably guess that rib 1 is the center. If rib 3 is at the edge of the sheeting than I'm close to a bal point. If the 2nd rib is at the outside edge of the sheeting than the 15OZ I just put in the tail is a drop in the bucket. I got the plane years age from a guy how was getting out of the hobby. I think he got it at a Pawn shop in Waco. It's a .40 size plane and it's got an Irvine 60 up front(that runs) Anyway, any input is appreciated. mk
